Time Voyage — Steve Brezenoff

On the first day of their spring break, best friends Tucker and Maya discover a "Special Collection" of Titanic artifacts at the local museum. But the artifacts have more power than they know. When they touch a magic ticket, Tucker and Maya find themselves transported 100 years in the past -- to Titanic's maiden voyage. Now they must figure out how to save a new friend, and return to the present, before time runs out.
