The Shape of Time (Rymworld Arcana #1)

First in the middle-grade mind-bending Rymworld Arcana adventure series from award-winning author Ryan Calejo.

The Shape of Time is destined to be an instant classic. Fourteen-year-old Antares De La Vega is a natural born adventurer. He dreams of journeying across burning deserts, trekking through wild and uncharted jungles, sailing the farthest reaches of the seas--and yet, he's never even stepped foot outside of South Florida. But that all changes when strange creatures come leaping out of lightning bolts to kidnap him. Locked away in a secret prison in the middle of the Bermuda Triangle, Antares meets fourteen-year-old Magdavellía, a mysterious and iron-willed girl who opens his eyes to a shocking truth: that this world is a far different place than he's been led to believe. 

Following a series of intricately concealed clues left behind by Magdavellía's parents (clues Antares seems to be the key to unlocking), they must wield both geometry and alchemy, outsmart molemen and mermaids, and outrun fiendish outer space aliens all while attempting to solve a riddle as old and mystifying as the sun.
