Shannon Kendricks thought all she had to do was venture to a strange world and face a giant race of aliens to save her friend Roebor. Boy, was she wrong. In this action-packed conclusion to the science fiction-fantasy trilogy, Power Rising, Shannon answers the call from the tiny Seladoran Salesti to travel to FireWorld to rescue her friend, the magnificent dragonpanther Roebor. She realizes that to save her friend, she must make a great sacrifice. To make matters worse, while she is on FireWorld, a terrible tragedy strikes, with consequences that will set Shannon on a mission fraught with danger. Back on Earth, as she seeks a way to overcome a Power of untold magnitude, she learns that to save her planet and the entire solar system, she may be required to sacrifice her life. Obstacles await her at every turn-dragonpanthers from FireWorld set on revenge, her Seladoran friend Essi trapped and in need of rescue, Homeland Security agents bent on discovering Shannon's secrets, and a FireWorld monster terrorizing whales in the Gulf of Alaska. With the help of her ever-loyal and beloved Luke, the indomitable attorney Tourmaline Kulkarney, and her cat Nascissus, Shannon attempts to fight through the obstacles and find a way to defeat the Power-and somehow stay alive.
