Query: a fascinating take on the Atlantis legend

If you like time-travel stories, this is certainly an excellent example of the genre. The author has definitely done a lot of research, and has created two delightful protagonists in Chloe and Cheftu. Which leads me to why this doesn't rate 5 stars--too much time spent on peripheral characters, and not enough on our hero and heroine! Pages would go by with no mention of the protagonists to the point where I wondered when they would return to the story. Aside from that, this is a very good series, and I'm looking forward to the next volume, which is due in August.
