Chronos Files Time Trial #4 (Of 4)

"Bestselling author Rysa Walker (Timebound) takes readers on a time-hopping adventure in this stand-alone series set in her Chronos Files world. Written by fan-favorite writer Heather Nuhfer (My Little Pony) and featuring pulse-pounding art from Agustin Padilla (Smallville). Clio returns to 1931 in a mad dash to save the ones she loves. In order to do so, she's forced to play a deadly game of safecracker, revealing, once and for all, the contents of Al Capone's vault."
