A murder mystery game turns deadly in this YA whodunit by the author of Suddenly a Murder.   
For fans of Karen M. McManus  Maureen Johnson  and Holly Jackson.   Everyone in town knows
about the game. For decades  J. Everett High has staged an annual murder mystery to put its
criminology students to the test. And this year  crime junkie Dulce Castillo is dead set on
winning. When the game kicks off  the student playing the victim  Xavier Torres  is found
poisoned in the school’s greenhouse . . . except his death is not pretend.     It’s murder.   
When the authorities open an investigation  all the evidence points to Sierra Fox  Xavier’s
ex-girlfriend and Dulce’s ex-best friend. Claiming innocence and desperate to clear her name 
Sierra begs Dulce to look past their bad blood and find the culprit.     After all  Dulce knows
this school better than any investigator ever could  but she must use caution to solve this
mystery. Because these historic halls are full of suspects with no shortage of motives. And in
this game of cat and mouse  the other player kills.
