Stephanie Tyler seems to write these books at a fair rate - I already have the next two in the series to read, and it feels as if I read the first two only a few months ago. Regardless, each story is a decent length and has a credible plot, although they are fairly closely interwoven so that someone who starts reading with this book might find it a bit tricky to pick up what's going on. That's my main gripe with the second and third books in this series: they feel like they start halfway through the actual story of hero and heroine since they have already met and begun a relationship in a previous book.

Our hero in Hold on Tight is Chris Waldron, the slightly psychic 'brother' who is also a sniper in the US Navy SEALs. In the last book, he met FBI Special Agent Jamie Michaels, and they had a brief but hot fling. This story attempts to draw out that relationship into something more significant as Jamie investigates Chris following a mission during which Chris's fellow operative was killed. At the same time, elements from Jamie's past may be coming back to haunt her, and she may have to learn to trust despite the inherent dangers.

A sub-plot about the relationship between Jamie's sister, PJ, and Chris's boss, Saint, is actually a more interesting and involving romance; those two unusual characters feel right together. The attraction between Jamie and Chris is less easy to believe in. However, the underlying plot - that of the danger threatening Jamie - works better than the previous books' forays into Africa. This author isn't particularly strong on characterization, but she keeps the plot moving reasonably quickly, and there's a wide enough range of characters for more interest.
