"Cynthia Hand is the master of pulling at your heartstrings. The How & the Why tells both sides of an adoption story with love, compassion, and care." —Brigid Kemmerer, New York Times bestselling author of Letters to the Lost

A poignant exploration of family and the ties that bind, from New York Times bestselling author Cynthia Hand.

Cassandra McMurtrey has the best parents a girl could ask for; they’ve given Cass a life she wouldn’t trade for the world. She has everything she needs—but she has questions, too. Like, to know who she is. Where she came from. Questions her adoptive parents can’t answer, no matter how much they love her.

But eighteen years ago, someone wrote Cass a series of letters. And they may just hold the answers Cass has been searching for.

Alternating between Cass’s search for answers and letters from the pregnant teen who placed her for adoption, this emotionally resonant narrative is the perfect read for fans of Nina LaCour and Jandy Nelson.
