Rowan & Ella Time Travel Adventure Books in Order

The Rowan and Ella Time Travel Adventure books are built around motion, chemistry, and historical danger. In this version of the series, the trilogy appears as A Trespass in Time, Journey to the Lost Tomb, and Race to World's End, three linked adventures that follow Ella and Rowan across centuries and into situations where love and survival keep getting tangled together.

Ella is the engine of the books. She is independent, quick to act, and not especially interested in being rescued, which makes her a good fit for stories that keep dropping her into eras where she has almost no natural advantage. Rowan is the steadying force and the complication at the same time, a man whose presence helps keep her alive even as their relationship adds its own emotional risk.

The historical settings are a big part of the fun. One book sends the story into Heidelberg in the shadow of a ruthless warlord, another into Cairo just before a legendary tomb discovery, and the last into old Key West with treasure, uncertainty, and maritime danger hanging over everything. Lewis uses those settings for action, but also for contrast. Modern assumptions do not travel well, and the books get a lot of energy from watching Ella and Rowan improvise.

These are adventure stories first.

That does not mean the romance is an afterthought. The relationship is what gives the trilogy its through-line. Each new era tests what the pair mean to each other and how much they are willing to risk, not just physically but emotionally. The books are full of escapes, reversals, and ticking-clock moments, but they keep returning to questions of trust, loyalty, and whether two people can build something lasting in such unstable conditions.

If you like time travel stories with plenty of forward drive, clear stakes, and a strong central duo, this trilogy delivers that mix very well. It is lively, fast, and built for readers who want history to feel dangerous and immediate.
