Indigo Peachtree has spent most of his life making toys for children. This kindly old toy-maker, however, has carried with him a secret he wishes to remain unknown. Yet as with most secrets they tend to come up to the surface over time. Tarquin Norwich, a ruthless lord, has come to learn about a journal containing everything Indigo desperately wants to protect. When the toy-maker goes underground, Tarquin seeks help from a witch, Mother of Craft, to go about finding other ways to obtain what he desires.

Mother of Craft tells him that in order to find Indigo, and his journal, he will need two outlaw brothers.

He sends his children, Archie and Clover Norwich, across the English Channel to snare the infamous outlaw, Pierce Landcross who knows the whereabouts of the journal.

Tarquin and his eldest son, Ivor, capture Pierce’s estranged brother, Joaquin Landcross, to find the missing toy-maker.

As Pierce is being pulled back to England, his dire situation flips completely around when he’s saved by a crew of Apache privateers known as the legendary Sea Warriors.

Instead of fleeing with his seabound mates, Pierce decides to return to England, taking Archie and Clover with him, to try and save his old friend, Indigo. Going back means Pierce will encounter old dangers as well as face a part of his past he would much rather leave behind.
