When Worlds Collide is the fifth and final book in The Dream Keeper Series.
Leviathan and Nitsua have joined forces to begin the War of the Worlds—with Earth as their prize. As the armies begin preparing for the greatest battle in the history of the worlds, Sarah discovers a truth that would prevent her from joining the fight. But with humans being forced to kill, and creatures being unleashed to destroy, Earth is crushing under the weight of the war, and Sarah may be the only one who can tip the scales in their favour. With her friends pre-occupied on Earth, and her people looking to her for hope, Sarah has a difficult choice to make—play it safe and secure on the sidelines… or risk a merciless death on the battlegrounds. The future of her kingdom is at stake and Earth hangs in the balance.
A grand finale to The Dream Keeper Series, When Worlds Collide defies the laws of traditional storytelling and will leave you questioning your own existence.
