Katharine Giles has created an excellent series that's engaging and enthralling. Dennis Waller

After his parents are lost at sea, 14-year old Archer takes the family trimaran and heads for Australia. Second thoughts make him abandon the trip but before he can head back, a killer wave throws him through a portal into the parallel world of the immortals. Archer arrives at the bottom of the sea with a few bumps on his head, a bad case of amnesia and a mermaid at his side.

The Crystal Trident, the first book of the Archer Adventures, plunges its reader into the ocean depths and a kingdom filled with danger at every turn. With no memory of his past, Archer begins a quest for a crystal trident on a journey that challenges his new-found skills. While he helps those who saved his life, he struggles to adapt to this alien world.

Through the long and dangerous journey, will Archer develop the needed skills that will let him find and return the trident? More importantly, will he discover his identity so he can go home or is he trapped forever in the land of the immortals?
