Can anyone reccomend some good historical fiction?

[Quintius Clavus]

I have read two of the proposed three books in Donna Gillespie's Light Bearer series. The second one, which I borrowed from the local library, has Trajan's Second Dacian War as a side plot-line, with the promise of more in the third book based on the cliff-hanger she leaves one with at the end of the book. I have not seen any information on the third one. The Dacian Wars are extremely rare as part of Roman historical fiction, at least among those written in English.
