Crocs (Sharks Incorporated, Bk. 3)

Marine biologist Doc Ford has a new mission for Sharks Inc.: visit Sanibel Island’s remote Bone Field to find a wild orange tree that's survived a disease destroying Florida’s citrus. There, the members of Sharks Incorporated find oranges unlike any they’ve ever seen, but can’t find the tree Doc needs. Worse, the area is protected by a massive saltwater crocodile.

What the team doesn’t expect is to meet a reclusive woman who threatens to call the police if they trespass on her land again. Reluctant to give up, the trio learns she needs help. When she was young, the woman found King Calusa's grave. Now, she believes the ghost of the dead king, who was beheaded by Spanish explorers 500 years ago, is haunting her.

To uncover the truth, the kids return to the Bone Field. The thousand-pound crocodile is determined to protect its hatchlings, but crocs turn out to be the least of their worries. The intrepid trio discovers the woman’s wealthy neighbor is selling illegal reptiles?and he knows the secret of the dead king’s missing gold medallion.
