Without a doubt, it is important to capture the reflections of a vice president who found herself in an unprecedented situation after the president was pressured to withdraw from the 2024 election. And “107 Days,” a taut, often eye-opening account — written with the help of Geraldine Brooks — takes you inside the rooms where it happened, as well as what led up to Kamala Harris’ remarkable run.

For one, apparently MSNBC’s Lawrence O’Donnell first gave Harris the idea she should seek the presidency in 2020. Harris and her husband, Doug Emhoff, were having breakfast at a restaurant near their Brentwood home when O’Donnell “wandered up to our table to talk about the dire consequences of a second Trump term.” Harris, then in her first term as a U.S. senator, recounts that O’Donnell bluntly suggested: “‘You should run for president.’ I honestly had not thought about it until that moment,” she writes in “107 Days.”

Later, Harris also reveals that Tim Walz was not her first choice for running mate: Pete Buttigieg was, though she ultimately concluded the country wasn’t ready for a gay man in the role.

“We were already asking a lot of America: to accept a woman, a Black woman, a Black woman married to a Jewish man,” she writes. She assumes Buttigieg felt similarly, but they never discussed it.

We do not glean much more than we already knew or assumed about President Biden’s life-changing 2024 phone call that set Harris on this path. Pleas for Biden to step aside had been building following his disastrous debate performance less than five months before the election, but by that time Harris had given up on the idea that he would withdraw from the race. But on Sunday, July 21, Harris had just finished making pancakes for her grandnieces at the vice president’s residence and was settling in to watch a cooking show with them when “No Caller ID” came up on her secure phone.

“I need to talk to you,” Biden rasps, then battling COVID-19. Without fanfare, he told her: “I’ve decided I’m dropping out.” “Are you sure?” Harris replies, to which Biden responds: “I’m sure. I’m going to announce in a few minutes.” In italics, we are made privy to what Harris is thinking during their brief phone call: “Really?” Give me a bit more time. The whole world is about to change. I’m here in sweatpants.”

If we wanted in on the powerful feelings that must have been swirling within each of them during such an exchange, or a nod to the momentousness of the moment — no dice. The conversation shifted to the timing of Biden’s endorsement of Harris, which Biden’s staff wanted to delay and which she wanted immediately. Politics, not sentiment, reigned.

The Atlantic book excerpt published earlier this month, it turns out, accurately represents the overall tone of “107 Days.” A thread running throughout is one of bitterness toward Biden’s inner circle, whom Harris felt had been poisoning the well since she first took office: “The public statements, the whispering campaigns, and the speculation had done a world of damage,” she recounts, and perhaps laid the groundwork for her defeat. While she had a warm relationship with the president himself, Harris believes she was never trusted by the first lady or the president’s closest advisors, nor did they throw their full weight behind her as the Democratic nominee.

At the same time, she never doubted that she was the right person for the job. She writes, “I knew I was the candidate in the strongest position to win. … The most qualified and ready. The highest name recognition.” She also calculates that the president and his team thought she was the least bad option to replace him because “I was the only person who would preserve his legacy.” “At this point,” she adds, “anyone else was bound to throw him — and all the good he had achieved — right under the bus.”

For those who are cynical about politics, “107 Days” will not alter your view. After Biden announces his withdrawal, First Lady Jill Biden welcomes Second Gentleman Emhoff into the fray, advising: “Be careful what you wish for. You’re about to see how horrible the world is.” Her senior adviser David Plouffe encourages Harris to distance herself from the president on the campaign trail, because “People hate Joe Biden.” Again and again, Harris provides examples of being left out of the loop or not robustly supported by his inner circle. She writes that her feelings for the president “were grounded in warmth and loyalty” but had become “more complicated over time.” She claims never to have doubted Biden’s competence, even while she worried about how he appeared to the public.

“On his worst day,” she writes, “he was more deeply knowledgeable, more capable of exercising judgment, and far more compassionate than Donald Trump at his best.” Still, his decision about seeking a second term shouldn’t “have been left to an individual’s ego, an individual’s ambition,” she concludes in an observation that grabbed headlines upon its publication in the Atlantic excerpt.

The exhilaration that Harris’ campaign frequently exuded in those early rallies is summarized here, but those accounts don’t capture the joy. Some of the details she chooses to highlight tamp down the excitement. For example, at their first rally together after picking Minnesota Gov. Tim Walz to be her running mate, Walz, Harris and their families greet an audience of 10,000 people in Philadelphia. Though Harris writes, “We rode the high of the crowd that night,” she also notes, “When Tim clasped my hand to thrust it high in an enthusiastic victory gesture, he was so tall that the entire front of my jacket rose up.” She makes “a mental note to tell him: From now on, when we do that, you gotta bend your elbow.”

The Kamala Harris I saw on the campaign trail and enthusiastically voted for is often in evidence on the page. She is smart, savvy, funny and tough. As in many of her stump speeches and media interviews, she tends to recite her accomplishments as if reading from a resume, which sometimes reads as defensive. But she is also indefatigable: She believes that she must win to save democracy, yet she seems to shoulder that formidable burden without breaking a sweat.

“107 Days” does an excellent job of conveying the difficulty of seeking — and occupying — high office, and suggests that if she’d won, Harris’ resilience and ambition would have served her well as the leader of the free world. Many of her insights are astute, though occasionally tinged with rancor. She does accept responsibility for certain missteps, such as when she was asked on “The View” if she would have done anything differently than Biden had she been in charge. She reflects that her response — “There is nothing that comes to mind” — landed as if she’d “pulled the pin on a hand grenade.” But she doesn’t attribute her eventual loss to that or any other miscalculation: She simply needed more time to make her case.

I craved a soaring moment, a rallying cry. I didn’t find hope or inspiration within these pages — the book felt more like an obligatory postmortem with an already established conclusion. If an aim of this memoir was to rally the troops for a Harris run in 2028, “107 Days” falls short of lighting a fire. The brilliant, charismatic woman who came close to breaking the ultimate glass ceiling has given us an essential portrait of an unforgettable turning point in her journey, but “107 Days” is mainly absent the perspective and blueprint for going forward that so many of us hunger for. A few years out, that wisdom may come.
