An extraordinary new novel from Jasmine Warga, Newbery
Honor–winning author of Other Words for Home, about loss and healing—and
how friendship can be magical.

Cora hasn’t spoken to her best friend, Quinn, in a year.

Despite living next door to each other, they exist in
separate worlds of grief. Cora is still grappling with the death of her beloved
sister in a school shooting, and Quinn is carrying the guilt of what her
brother did.

On the day of Cora’s twelfth birthday, Quinn leaves a box on
her doorstep with a note. She has decided that the only way to fix things is to
go back in time to the moment before her brother changed all their lives forever—and
stop him.

In spite of herself, Cora wants to believe. And so the two
former friends begin working together to open a wormhole in the fabric of the
universe. But as they attempt to unravel the mysteries of time travel to save
their siblings, they learn that the magic of their friendship may actually be
the key to saving themselves.

The Shape of Thunder is a deeply moving story, told
with exceptional grace, about friendship and loss—and how believing in
impossible things can help us heal.
