The Riddles of Epsilon

When Jess and her family move to Lume, a remote island off the coast of England, strange things start happening. Jess discovers an abandoned cottage on her family's property and an eerie presence within. The spirit, Epsilon, leads Jess to a set of three locked boxes, which she can open only one at a time. Inside, she discovers antique papers that set her on a path to unravel a series of riddles and codes that will somehow help her uncover the secrets of Lume.

The boxes also contain the writings of Sebastian, a boy who lived on Lume a century apart. Jess discovers that both of their mothers share the same obsession and will be driven to madness. And both Jess and Sebastian have the same foreboding dreams -- a hundred years apart.

On Lume, where nothing is what it seems, Jess must unlock the riddles of Epsilon in order to save her mother and place an ancient relic in the right hands -- but whose? Guided by the mysterious Epsilon, Jess has limited time to solve the mystery and dispel a curse that has hung over the women in her family for centuries.

Spine-tingling and eerie, The Riddles of Epsilon is a riveting read for teens.
