My first 5-star read of the year hit all the right notes for me - an adult mystery about a dead billionaire and the treasure hunt he sets up and the cast of characters who want to solve the puzzle. Led by a whip-smart and engaging heroine (the black-clad Tuesday herself), it's simultaneously a puzzle box, a noir, a coming of age story, a ghost tale, an ode to the power of pop music, and an immensely satisfying story. I can't wait to see what this author does next.
