Ellen Potter

On an island off the coast of Maine, where children ride lobster boats to school, Piper wants a horse but finds, instead, another object hidden in the red maple tree.

Hidden in the fairy hole of the red maple tree are x-ray vision glasses that Piper takes to school to use as her class learns about traveling to China.

As they uncover their magical powers, Nell and her new friends discover a parallel New York City called the Nigh, where monsters roam Central Park, Finfolk haunt the Hudson River, and a terrifying Minister, who controls it all, holds the key to Nell's missing brother.

"Hugo is a young Sasquatch who longs for adventure. Boone is young boy who longs to see a Sasquatch. When their worlds collide, they become the unlikeliest pair of best friends"--

Hugo is a young Sasquatch. Boone is a young boy. After an unlikely encounter, they've become an even unlikelier pair of best friends. After saving up his Monster Card wrappers, Hugo sends away for a special prize in the mail -- a Monster Detector! Using the watchlike device, Hugo quickly spots a monster right in his own cavern. Spooked, Hugo heads to school and finds yet another surprise -- his friend Boone! Boone announces he wants to go to Sasquatch...

Determined to buy a Marvelous Monster Magnet, Hugo and Boone set out to earn the money on an adventure through the woods, where they meet some interesting new friends.

Weeks after discovering the Nigh and leaving her brother behind, Nell and her friends are given the opportunity to become Watchers, but they must pass three challenging trials with their Nigh creatures called Fates, while also evading the Minister and her Magicians.
