New York Times best-selling author and guest artist Riccardo Burchielli conclude their three-part Earthdivers Ice Age adventure!

Bound and boarded onto a skin boat headed across ice floes and frigid seas, she has one last, unlikely shot at getting out of this alive: SHARKS. Giant, ravenous, prehistoric sharks.
