Detours in Time by Pamela Schloesser Canepa

Book 1 of the Detours in Time series

Young, fiery Tabitha takes a whirlwind trip to the future with Milt, an awkward Science professor. Wonders and curiosities abound. However, their amazing journey soon becomes a race through a maze of challenges and difficult decisions. When an unplanned detour occurs, the two set events into action that may have saved one life only to destroy another. Can these friends of completely different mindsets agree on a course of action that will get them back home without undoing the future they're growing so attached to?
Detours in Time is a fantastic escape that presents many moral dilemmas and surprises that will either destroy the strongest of friendships or bring two people even closer.
