In all fairness, gladiators are not my slice of salami.
I read this book for a challenge because of the Mars character. He disappointed me a quite a bit, since his true nature never got a chance to shine. As for the mortals, as entertaining their relationship was in the beginning, it all turned to lust and then love all too quickly, at the same time failing to produce any hint of chemistry between them.
The book is short, and of course, it limits the opportunities for the characters and relationships to develop fully. The plot was a bit of a cliche, the chemistry, like I said, was non-existent, the sex was meh.
