PositiveThe Harvard Crimson... a fascinating and cleverly written exploration of the relationship between two close friends, but it unfortunately struggles with handling its multiple plotlines in the book’s later sections ... It’s a lot of material to juggle in just one novel, and Zevin accomplishes this with skillful dexterity. A book about video games might seem daunting to those who have no knowledge about gaming, but this novel is more about human relationships than it is about video games. And in places where understanding the technical side of video game development becomes necessary, Zevin walks the reader through the process step by step ... The book’s strengths lie in its characters, though, and the plot ultimately takes a backseat to the relationships between its three main characters. Sam, Sadie, and Marx are all realistic and sympathetic characters who one can’t help but root for despite their flaws. Through them, the novel depicts a compassionate portrayal of the messy dynamics of a long, complicated friendship ... Zevin also does a wonderful job immersing the reader in the book’s multiple settings ... Unfortunately, around the halfway point, the book starts to drag. Tomorrow is over four hundred pages long, and the plot doesn’t quite justify its length ... pulls itself together at the end, though. The last fifty pages again show Zevin’s skill as a writer, as she brings together several plot threads to produce a poignant finale. Although the plot meanders on the way to its final destination, it does get there eventually, and the destination is exciting and emotionally satisfying ... Although its second half struggles with uneven pacing, Tomorrow, and Tomorrow, and Tomorrow is worth the read. The book reaches unflinchingly into the messiness of our complex and often mysterious world, joyfully revealing to readers what it means to be human and to be a friend.
