Starred Review
If Tomorrow Doesn’t Come begins on Avery Byrne’s nineteenth birthday morning. She’s walking to the river on campus, where she plans to drown herself. She’s written good-by letters and is ready to go.
But she’s interrupted by the news that a giant asteroid is going to strike the earth in nine days. It’s looking likely that not just Avery, but everyone she loves is about to die. That wasn’t how it was supposed to work.
Avery’s at an ivy-league university in New Hampshire, but she gets a call from her best friend Cass – at Pratt Institute in New York City – to meet in Boston. And Avery can’t help but promise to be there. She ends up traveling in a van with her roommate, Nigerian-born Aisha, and the professor who failed her first semester, along with his dog.
After some adventures meeting up with Cass in Boston, most of the book is set in Avery’s home town of Kilkenny, where her parents think they can make a bunker in the basement and survive the catastrophe. The asteroid is going to hit in Arizona, so it’s possible they might make it, if they can stockpile enough supplies.
The story plays out in the days leading up to the asteroid strike. And no, we don’t find out if they survive – not knowing and how you would live not knowing is what the book is about. The stories of the present are interwoven with stories of the past and what led to Avery’s deep depression.
Part of that is she’s long been in love with Cass, but wasn’t able to come out to herself as lesbian, let alone her family and friends. When the future is uncertain, somehow that seems more important.
The characters are nineteen, and there’s a somewhat detailed lesbian sex scene, so this isn’t necessarily for younger teens. This book is primarily about depression and seeing all you have to live for, as well as the importance of living for yourself, and not simply for others.
There are no pat answers in this book, but it’s beautifully expressed. I have to say that the writer shows Avery’s emotions so effectively, the book was a little sad to read. But it also realistically showed Avery coming to terms with her own attitudes that helped lead to her depression. And we believe in her plans to get a therapist and maybe take medication – if they all survive.
But I can’t express how beautiful and uplifting this book is despite all that. Avery does find joy and reasons to live. I was reading this book for the Morris Award, but my first time through, was so immersed in the book, I didn’t take much time to think critically about it. Whatever our committee ends up deciding, I highly recommend this book.
