Two worlds. One forbidden love. A forgotten truth that could change everything. Seventeen-year-old fairy princess Isla has lived her entire life bound by one sacred law: never cross the forbidden waters separating the Fairy Realm from the human world. Then one impossible choice changes everything. When Isla secretly saves human Jason Marshall, she sets into motion a chain of events that threatens not only their growing bond, but the future of every magical kingdom. As Jason searches for the mysterious girl who saved his life, he discovers a hidden world filled with breathtaking beauty, ancient magic, and dangerous secrets-one he was never meant to find. While forbidden feelings slowly grow between them, war looms across the Northern Territory. Prince Kai is sent to defend the Fairy Realm against the ambitious Elven King, Cirrus, whose hunger for land and power pushes the kingdoms toward devastating conflict. When Kai's cousin Flynn disappears during the brutal campaign, a desperate search uncovers long-buried secrets that challenge everything the Fairy Realm believes about its own history. As ancient scrolls reveal that centuries of fear have hidden the truth behind the kingdom's most sacred laws, Isla, Jason, and Kai must choose between protecting the world they've always known or risking everything to restore the ideals their ancestors once fought to preserve. Filled with unforgettable characters, breathtaking magical landscapes, epic adventure, political intrigue, family bonds, and a slow-burning romance, Forbidden Worlds Collide is a sweeping fantasy about courage, sacrifice, forgiveness, and discovering that love has the power to heal even the deepest divisions.
