In this action-packed thriller sequel to Envy, foreign exchange student Olivia Grant is stabbed to death after a party--and the prime suspect is her best friend. As twins Hayley and Taylor Ryan get pulled into the aftermath of this Amanda Knox-like crime, they realize nothing is what it seems. Could it be betrayal of the ultimate kind?

Betrayal features real-life crime-solving techniques, heart-stopping suspense, plenty of red herrings, hard-hitting ethical questions, and information about the Amanda Knox case that inspired the novel. As the crime unravels, so does the twins' past…and they must face off against a family member who may unexpectedly have carried out the worst betrayal of all.

"In their debut, Envy (2011), the girls uncovered the truth about a recent death, but the death they're involved with now is clearly murder. Adult characters are more defined than in many novels for teens, with S'Kallam Tribal Police chief Annie Garnett and Mindee the hairstylist at the forefront. The third-person narration allows Olsen to. . . keep the suspense going and the mystery intriguing. . . . there is plenty of action, as well as many snide remarks and unlikable characters, to keep readers' attention.” --Kirkus Reviews

Praise for Gregg Olsen's ENVY:

“Gregg Olsen's Envy is a riveting page-turner that I could not put down.  Like Jay Asher's Thirteen Reasons Why, Envy explores a serious topic--cyberbullying--in a fantastic, well-crafted story.  Can't wait for the next Empty Coffin novel!”--Nancy Holder, New York Times bestselling author of the Wicked saga, Dear Bully contributor
