As per above title. =P I've been a huge fan of roman romance since "spartacus" and "300".

Some that I particularly love;
Enslaved - Virginia Henley
My wicked gladiators - Lauren Hawkeye

There's others that I've read, such as Love, eternally by Morgan o' neill, Mask of the gladiator by George Lee and a few other roman eroticas that has 0 story plot and not worth mentioning.

I would really appreciate if any of you could recommend some great roman novels (doesn't matter paranormal/time travel). Much thanks in advance!

Worth by Shay Savage.
It's a short story, but definitely take a look, I thought it was great.
