The Darkest Summer

One hot summer, Dee disappeared. Now she's back . . . but she's not the girl you knew.
Sera and Dee were the best of friends.
Until the day that Dee and her brother Leo vanished from Sera's life, during a long hot summer fifteen years ago.
Now Sera is an adult, with her own child, five-year-old Katie, and has returned to her childhood home after her husband's death.
While she grieves, the past haunts Sera at every turn . . . and then Dee and Leo return to their small Hampshire village, along with Dee's young daughter.
But Dee is silent and haunted by her demons; no longer the fun-loving girl that Sera loved. And when Sera uncovers the shocking secret that Dee is hiding, it's clear that the girl she knew is long gone-and that the adult she has grown into might put all of them in danger . . .
