You, Me, Naideen and a Bee by Ken Ramirez

For thousands of years Middle Earth has lived under a curse that threatens to completely destroy the fairy world if the prophetic chosen fail to meet their destinies. White elves, Brodie and Naideen, have watched over the family lines of two humans carrying the blood of the ancients within their veins. When the chosen, bearing the birthmarks of the prophecy, are born in the human dimension they will be transported to Middle Earth in their sixteenth year. Unbeknownst to Jamie and Julia, the human-elf Task Bearers, and Allie, The Guardian, they are about to embark on a journey that will immerse them into the world of elves, trolls, dwarves, magical dragons, wizards, and the evil sorceress, Lady Celina.
