Matt Killeen 
Devil, Darling, Spy 

A teenage spy.
A killer disease.
And the monster who would use it.
Sarah is used to spying in the champagne-fuelled parties of Nazi Berlin. But now she must track a deadly virus through central Africa and unmask the mysterious White Devil before the disease can be turned into a weapon.
SURVIVE. DECEIVE. RESIST.
They think she is a terrified little girl. But she is a warrior set to burn them all.
