Seven Wonders is a pentalogy of children's fantasy, adventure and mythological fiction books written by American author Peter Lerangis.

The day after thirteen-year-old Jack McKinley is told he has six months to live, he awakens on a mysterious island, where a secret organization promises to save his life—with one condition.

Jack and three other kids: Aly Black, Cass Williams, and Marco Ramsay, must lead a mission to retrieve seven lost magical objects known as Loculi, which can save their lives only when combined together correctly.

The first Wonder they visit is the Colossus of Rhodes, where they realize that there is way more than just their lives at stake when a mythical creature kidnaps Cass and an enemy organization, known as the Massa, threaten to get the Loculus before them.

A giant, merciless behemoth guards the opening to the rift, and so Jack McKinley and his friends realize that rescuing Aly will be a lot harder than they thought.
