Aj Torres and the Treasure of Captain Grayshark (Carton of 12 Hardcover Books)

A swashbuckling tale of friendship, courage, and ghost pirates! Join twelve-year-old AJ and his friends on an epic adventure to find the long lost treasure of Captain Grayshark.

When AJ and Jayden discover a gold coin washed up on the shore of Miami after a hurricane, they think it might be the answer to all of their problems.They suspect the dingy old coin may be part of the long lost treasure of Captain Grayshark, whose loot was valued in the millions. That much money could help the Torres's sinking family business and more importantly, allow Jayden to stay in Miami with his mom, instead of moving miles away from his best friend. The boys set out on a quest, along with resident ghost expert, Andrea Wade, to unearth the pirate's treasure on a nearby haunted island.
But the pursuit of treasure might prove more perilous than they could ever imagine--with treacherous waters and a crew of angry ghost pirates waiting for them on Scream Island . . .
A slightly scary, laugh-out loud adventure about searching for gold, but finding much more along the way.
