This trilogy of books is a must read. In The Dark by Lynette Eason you meet Steph Cross helping Tate Cooper find out who killed one of her best friends and why. Great suspense and you can't figure out the bad guys till the end.
In Downfall by Lynn Blackburn you meet Chef Cassie Quinn who must lay aside some old fears and help Donavan Bledsoe figure out who hates her and her cooking enough to destroy her livelihood. Great mystery till the end.
In Perilous Obsession by Natalie Walters, you'll help teacher Lahela Young and Briggs Turner figure out who holds a grudge and why. All three of these books are page turners and you don't won't to stop reading. Highly recommend this book by three great writers.
