Science doesn’t always have to be serious.

Anthropologist Ava Simms is an expert in the art of seduction–hypothetically. Theory and reality are two different things. When she’s given the chance to write a book on all she knows, she quickly discovers she needs hands-on practice.

Reluctant ghostwriter Ian Cole is hired to help Ava streamline her ideas–on paper. He has his own projects to pursue and fixing someone else’s isn’t in his plans, but he owes a favor. He expects to work with a stodgy professor, not a knockout wearing little more than body paint, who sets him aflame. Sign him up for overtime.

Their instant heat is unprofessional, inconvenient…and irresistible. Ian wants Ava and Ava wants Ian. Why argue with biology? Especially when they share the same desire: pleasure on the job, no commitment.

Except what happens when the book is done and they both want more? One thing about fire–if you’re not careful, it burns.
