What Is Lost by Lauren Skidmore is a rare novel length retelling of Little Red Riding Hood that was published in 2015. The red hood is an assassin's cloak in this one which I imagine is a form of catnip for some of the readers here!
Angry at his failure to exact vengeance on the prince, mask maker Joch flees Venesia to find his lost love. When a red-cloaked assassin promises answers, he has little choice but to trust her though he maybe walking into a trap. Unravel the deception in this dazzling story of second chances that will keep you guessing to the last page.
"The plot's twists, turns, and lurking dangers will keep Skidmore's fans engaged all the way to an ending that will take even the most astute reader by surprise." --Booklist
