Pat O'Toole has always idolized his older brother, Coop. He's even helped Coop with some of his crazier plans—such as risking his life to help his big brother dig a tunnel underneath their neighborhood in the suburbs of Washington, DC. Coop is... different. He doesn't talk on the phone, doesn't use email, and doesn't have friends. He's never really cared for anything but the thrill of being underground and Pat. So it's no surprise to anyone—even Pat—that after a huge fight with their parents, Coop runs away. Exactly one year later, Pat receives a package containing a digital voice recorder and a cryptic message from his brother. He follows the clues to New York City, and soon discovers that Coop has joined the Community, a self-sufficient society living beneath the streets. Now it's up to Pat to find his brother—and bring him home.

Troubled waters! Cryptids–mythological creatures like the Loch
Ness monster and Sasquatch–are Travis Wolfe's obsession, and he'll travel to
the ends of the earth for proof. For cousins Marty and Grace, who have lived
with Wolfe ever since Marty's parents disappeared, this means adventure–
and danger! Now they're all en route to the South Pacific to track down a giant
squid, but the freighter they're on seems to be haunted, and someone on board
is determined to saBobotage their mission. Will Marty and Grace get to the
bottom of this fishy business, or end up at the bottom of the sea?

The riveting sequel to TENTACLES and CRYPTID HUNTERS,
reunites Marty and his unusual uncle, cryptozoologist Travis Wolfe, as they
search the world for Wolfe's daughter, Grace. Grace has been kidnapped by her
grandfather, the ruthless and dangerous Noah Blackwood, who has also stolen
the two dinosaur hatchlings Wolfe was raising in secrecy. Now, with word that
the mysterious creature known as Chupacabra has been sighted again, Wolfe is
torn between his obsession with finding cryptids and his desperate need to
rescue his daughter. With trouble at every turn and a dangerous journey
ahead, will Marty and Wolfe come face-to-face with the mythic monster? Even
more frightening, will they reach Grace before it's too late?
