Robert York is a time traveler and he is going back to prehistoric times to the Stone Age "just to observe and study the inhabitants of Kent's Cavern." And we all know how that's going to work out, right? Humans seem to be humans no matter where or when they are.
Robert saves the life of one inhabitant minutes after his exit from the rainbow portal. So much for not messing with the timeline. Then he proceeds to insinuate himself into the everyday life of the people and to promptly fall in love with his host. This well-written story is a story of love with a little time traveling thrown in and it's just made for readers who like the emotions and interactions and historical details rather than lots of action.
Things get more interesting as Robert returns to the 24th century and his love tries to follow him, only to end up in the twenty-first century. Punishments happen for not following rules, and Stone Age girl is befriended by Nikki of 2006 who has her own way to live life, including rescuing total strangers. A little comedy and drama take place as Future Big Boss sends back thugs to force the girl back to the caves, Nikki fights them off with a shoe, and Robert (again) breaks the rules and gets his friends to help him jump to 2006 to find his love. You'll be glad you invested the time in this book, which begs for a sequel with some of the same characters.For Honor: An Adventure of What Might Have Been: Book One of By Honor BoundGambit for Love of a Queen: Book Two of the Series By Honor BoundRighting Time: Book Three of the Honor Bound (By Honor Bound)Out of Phase: A Time Traveler's Chronicle: Book Four of By Honor Bound
