It's about the mermaid principessa Serafinna and her friends, who after separating to find the 6 talismans get into trouble in the mirror realm, Atlantis and Cerulea and Matali. Some of the trouble includes the dragon species called razermouths, an ifanta and kobolds. The ending was so good but unfortunately it was the biggest cliff hanger in the world and I have to wait till October to read the third book!
