Ultimate Popsugar Reading Challenge discussion

I have the following books on my list to read and I'm trying to fit them into categories for the challenge: The Rembrandt Affair, The Diabolic and Into the Forest.

Into the Forest is the Paula Guran anthology?-maybe "multiple authors","mythology","genre dont normally read"..:-)

The Diabolic is a first book in a series

Into the Forest by Jean Hegland

Sorry-not familiar with it :-)
