Rescuing Awen

Dell's life sucks.
His father has disappeared, his grandfather died under mysterious circumstances, and this morning after defending the new kid from the town bullies, he discovered the new kid is an alien who came to Maine looking for Dell's grandfather. When Dell follows the new kid through a portal onto another world, he meets Awen, a sentient planet, to whom he is telepathically linked. Awen is dying at the hand of ruthless off-worlders who are determined to control Awen's wormholes. When Dell learns Awen is awaiting his grandfather to arrive and save her, Dell agrees to replace his grandfather and defend the ailing planet. Gaining the power to manipulate Awen's elements of Earth, Air, Fire and Water, he uses his new superpowers to overthrow Awen's enemies and find his missing father.
