Deadly Cool 
Deadly Cool Mysteries book #1 


First I find out that my boyfriend is cheating on me. Then he's pegged as the #1 suspect in a murder. And now he's depending on me to clear his name. Seriously? 

As much as I wouldn't mind watching him squirm, I know that he's innocent. So I'm brushing off my previously untapped detective skills and getting down to business. But I keep tripping over dead bodies, and I'm still no closer to figuring out who did it. And what's worse: all signs seem to point to me as the killer's next victim. 

I really need to pick a better boyfriend next time.

The Deadly Cool Mysteries are getting a whole new look, and will be re-released in all ebook formats in 2020...along with the along-awaited book #3, Wicked Games!
