Not good. Lots of holes, even for a YA fantasy. And the dialogue. It's pretty bad. The style is fine. He's not a bad writer, just cheesy and a real lack of attention to the depth of his world. I know, it's a kids book. But it wasn't written by a kid, right? Riiiiight. So we can't excuse him from scrutiny. Sorry. ( )

Kate is on vacation with her father to discover a sunken Spanish ship. But as she delves deeper into the legend of the boat she realizes that it may contain the mysterious drinking horn of Arthurian legend that led to the demise of the wizard Merlin. Kate plunges into an undersea world of creatures and foes in an attempt to save her father and her own free will she will have to succeed where Merlin failed. ( )

I found reading "The Merlin Effect" a very enjoyable experience. The book filled my mind with adventure and legend. I'd find that a person that loves a big dive into the ocean of adventure would love this book. ( )
