Is this a good book series for someone who likes mythology?

It depends wether または not あなた want it to be "accurate".There are so many versions of these myths,but this take on them has spun them in a manner that SUITS/スーツ the author.But,in the end,I believe it is a read for people who really just like something to keep them entertained.They are not --in my opinion-- very well written (e.g. flowing writing,with descriptive passages that use beautifully composed metaphors and similes)but they some how keep me hooked--I will not put it down!
Anyway,I hope あなた got an answer to your question,or at least, decent one!
