Cressida Frost is in a bind. The home and business she shares with her sisters are in jeopardy as the landlord threatens to sell the property out from under them. Her only hope is to win a four million dollar treasure hunt prize, buy the house, and save Frost Fandoms Bookstore and Collectible Shop. The only hitch in her plan: as an agoraphobic, the thought of traveling across multiple states to find the prize is more than daunting. Noah Sukarno is in over his head. When trouble arrives on his doorstep and threatens his family, he knows he has to win the treasure hunt prize. He and Cressida have known each other for years through the contest fan boards, and he knows she is closer than anyone else to finding the treasure. However, his brilliant plan to volunteer to help her to get closer to the prize may just blow up in his face. Agreeing to travel together in an RV painted to look like the TARDIS, Cressida and Noah both have a lot riding on finding the treasure. Working together to overcome her panic attacks and his sense of impending doom, they realize that the biggest risk may be to their hearts. Will mistrust and betrayal tear them apart, or will love prove to be "bigger on the inside?"
