Be sure to read Twilight Streets next - there's some *great* Ianto crack in it. :)))

Actually, if you know you are going to read all three anyway and sequential order is important to you, there is a noticeable progression/parallel to the second season - I read them in reverse order and it did bother me a little so you might just want to be patient and do them in order.

They go like this:

Something In The Water by Trevor Baxendale
Trace Memory by David Llewellyn
The Twilight Streets by Gary Russell
