Akasha, The Complete Saga

This is the boxed set of all four books in The Akasha Series; Water, Air, Fire and Earth.

Water: Elemental powers in the palm of her hand…
…and it won't be enough to save her. When Kaitlyn Alder is involuntarily introduced to a life of magic, she becomes part of an organization hell-bent on saving the Earth. Just as her newfound life holds promises of purpose, romance, and friendship, the organization divides and a rogue member holds Kaitlyn hostage. Now one of the most terrifying men the human race has to offer stands between her and Earth's survival.

Air: She carries more than elemental powers.
In 'Air', the sequel to 'Water' of the Akasha Series, Kaitlyn has a secret. One she won't be able to hide much longer. As the strongest Gaia the planet has ever seen, she must face mankind's greatest enemy as he campaigns for 'One Less: Depopulation'. Everything depends on Kaitlyn fully embracing her role as Gaia. Her family. The Seven. The Earth. Something has to give, and it won't be Kaitlyn.

Fire: Elemental magic is a weapon of power, on both sides of the war. The Seven has another leader, Kaitlyn is a new mother, and everyone is busy building their armies. During one battle, the secret to Akasha is discovered, and the race to master it is on. With all eyes on the prize, what matters most gets left behind. It is up to Kaitlyn to preserve the planet in the wake of the pure destructive power of Akasha, and the humans who wield it.

Earth: After an elemental apocalypse, the fate of Earth hangs in the balance. The hunt for Micah in a world that has gone dim leads Kaitlyn straight to Shawn and One Less. While struggling to survive, she battles a side of her that is as dark as the rest of the planet. In the exciting conclusion to The Akasha Series, our heroine is no longer a part of The Seven or One Less. Now she is on Team Kaitlyn; who will join her?
