'Collin is obsessed with coins—collecting them, stacking them, and using them in magic tricks. One day, his misguided dismissal of a cautionary legend lands him in the clutches of Margarash, a monster who also loves coins. Locked in a cage in Margarash’s lair, deep within the cushions of his parents’ couch, Collin must think fast if he is ever going to escape and make it back home!
'A surprising book that is also a little scary and more than a little deep, Margarash is about a young boy and a seemingly-nasty monster who realize they need each other.'
