Ashes, Ashes, They All Fall Dead — Lena Diaz

This nursery rhyme will keep you awake.

What she doesn't remember ...

One by one the letters arrive at the FBI office in Savannah, Georgia. Inside, each bears a name--a victim of a twisted crime--and the singsong phrase Ashes, ashes, they all fall dead. Special Agent Tessa James becomes obsessed with finding the killer whose victims are crying out to her for justice.

Will kill her ...

When sexy, brilliant consultant Matt Buchanan is paired with Tessa to discover who's sending the "Ashes" letters, he discovers a serial arsonist who is leaving nothing but murder in his wake. Inexplicably, the clues point to Tessa herself, forcing her to realize that if she can't remember the forgotten years of her past, the name on the next letter will be hers.
