The Infinity Caverns (Parallel Society #1)
Roni works in her family bookstore and soon learns that Grandma and Grandma’s two pals have been saving the universe for decades. But it’s hard to keep that up with a bad back and arthritis. They have a simple solution, though — train Roni to take over.
Tossed into a new reality that she never expected, Roni must decide if she will step up and join the team or forever leave behind all she has learned and all she cares about.
Oh, and she’ll have to save the universe, too.
