Perfect for fans of Percy Jackson and Mr. Lemoncello’s Library, Atlantis: The Accidental Invasion is now in paperback! Kaya, raised in the undersea, high-tech world of Atlantis, has always been fascinated by the legends about life above the water.

In the world above, where climate change has led to giant tsunamis that threaten Earth’s coasts, all Lewis wants is to spend more time with his scientist father. When he stows away on his dad’s top-secret research trip, he finds himself thrown headfirst into an adventure much bigger than he bargained for.

From the author of the Pegasus series comes a spellbinding first book in a new fantasy series for fans of Rick Riordan and Shannon Messenger following two cousins whose summer vacation gets swept away by a storm that lands them on the lost island of Atlantis. The last way that Riley Evans wanted to spend spring break was studying whales on the family sailboat in the middle of the Bermuda Triangle. With only her dad, aunt, and annoying cousin Alfie for company, she is so bored staring at the waves that she’s starting to see mermaids between them. But when their boat is capsized during a sudden storm, Riley finds more excitement than she bargained for as she and Alfie are washed ashore with neither of their parents in sight. Where they’ve been shipwrecked is no deserted island, though. Atlantis is a place beyond imagination, inhabited by both people and incredible creatures ranging from unicorns and gargoyles to talking animals. But not everyone welcomes the cousins’ arrival, and beneath the wonder of this mythical land lurk dangerous secrets—something strange is happening to the inhabitants. What Riley wants more than anything is to find her father and go home. But the closer she gets to this goal, the more the islanders seem determined to keep her from reaching it. As Riley and Alfie unravel the mystery of Atlantis and its most terrifying part, the Forbidden Zone, they realize that the clock is ticking. If they can’t learn what happened to their parents and find a way off the island soon, it may be too late to leave.

"Describes the unrecorded history of humanity with a particular emphasis on Atlantean civilization; presents a vision of our true destiny as guardians of Earth and free-willed, conscious participants of our evolving world"--Provided by publisher.

Geneticist Kate Warner and counter-terrorism agent David Vale are working desperately against the clock to prevent a pandemic 70,000 years in the making. If this plague takes hold, it could change humanity forever...

Ancient monuments all over the world - from the Pyramids of Giza, to Mexico, to the ancient sites of China - are also awakening, reacting to a brewing crisis not of this earth, connecting to each other in some kind of ancient global network. A small group of scientists is assembled to attempt to unravel the mystery. What they discover will change the world. Imagine that 12,000 years ago it really did rain for 40 days and 40 nights. That storms reigned supreme. Imagine that survivors of human civilization really were forced to take to boats or hide out in caves on mountaintops. Then consider that these same myths from around the world predict this kind of devastation will occur time and again. What could cause such a catastrophe? What occurs in nature with such frightening and predictable regularity? A pulsar. But this is not just any pulsar - the ordinary type that pulses once a second, a minute, or even a week. This pulses once every 12,000 years and sends out a gravity wave of such ferocity it beggars belief. Not only that, it's closer than anybody has ever imagined. For it lives in our own backyard. It is the Sun.
