Shinji Takahashi and the Mark of the Coatl is a young adult novel by Julie Kagawa based on the Society of Explorers and Adventurers.
Summary[]
Shinji Takahashi is just an ordinary kid. An ordinary homeschooled smart-alecky orphan kid being raised by his aunt Yui. But when a magical guardian decides to use him as a conduit to awaken its power, Shinji’s life takes a turn for the extraordinary. Captured by the menacing Hightower Corporation, which is bent on using the guardian’s magic for its own nefarious purposes, Shinji must team up with a brilliant young tech whiz named Lucy and her robot mouse, Tinker, to escape the Corporation’s evil clutches.
Together Shinji and Lucy turn to the venerable Society of Explorers and Adventurers and its ragtag cast of spelunkers, hackers, mapmakers, pilots, and mythology experts (among other things) to return the guardian to its rightful home and release Shinji from its magic—which seems to be draining his life force. Time is ticking, the Hightower Corporation is hot on their tail, and success or failure might depend on one small thing—Shinji finally coming around to the belief that he is anything but ordinary.
