May have appeal as a sort of "girls' Artemis Fowl" (I hate to say it that way, because I don't believe in gendering readerships, but if the shoe fits) - but this book lacks Colfer's early books' tight plotting and strong continuity editing. There is a female protagonist who at first realistically struggles with riddles placed before her, but who unrealistically transitions from a stereotype (parent-hating drinking/smoking high school freshman) to a person in far too few pages, who lives in a world more suited to a Clive Barker Abarat than in the realistic, chatroom-transcript-enabled world she inhabits, and whose mother steals all the plot thunder without any of the character lightning at the end. The riddles are also unnecessarily abstruse and the climax far too deus-ex-something to appeal to readers who could be captured by the narrator's attitude at the beginning.

There are original elements, there is a code that Fowl fans might enjoy breaking (though it's a bit too easy for Colfer fans to enjoy cracking), and there are secondary characters who, in a novel for advanced readers and adults, could have been developed into interesting people, namely the father and mother, but the villain and magic guide are not characters at all - merely plot drivers - and the unimpressive typesetting for "handwritten" portions and "handwriting" on the illustrations make this look like a self-published piece rather than one that was edited and produced by a professional. Overall, I think the author could have done with firmer editorial guidance and the book with a better designer, and the main character's back story needed to have been reverse-engineered to provide some reason that she could become a character worth the reader's attention through all the twisty riddles. - Also, don't read the epilogue. It enervates the "magic" elements altogether. ( )

It's such a good book, I don't like reading that much but this book is REALLY GOOD. There is great suspense and mysterious elements that makes the book better. I think the idea is very common but the writer makes it different by adding her own twist to this story.

PC: If any of you like mystery books and/ or solving riddles, this book is great.

Its about a girl, Jess, who was recently expelled from school and was forced to moved with her mum to this fictional island called Lume. When she is online chatting with her friends, she gets mysterious messages from a person called 'V'. 'V' makes her visit places around Lume, and says that she and her Mum are in great danger. The island has a haunting past, and it is Jess' role to save it from coming back and taking her Mum.

It is really is a great book and you can't put it down. Each chapter you are given more clues and surprises. Although, I do have to admit, the book can get scary at times, especially if your home alone at night. So if you're a bit of a scaredy cat like me, I suggest you read this book when other people are around and it's not midnight.

The whole book is full of connections and if you're the type that really gets engrossed in a book, make sure you have a pen and paper next to you. Trust me, you're going to need it if you want the figure out the first few mysteries.

So if you like suspense and mystery, and can't find a book to read, Riddle of Epsilon is perfect. ( )

It's a really good book ,very interesting ( )

Started off really well but then became a bit boring. Didn't really like any of the characters and I felt the book just went on too long. ( )

Elly says: Slow start, but it picks up, gains momentum and gets down right creepy at times. Epsilon is mysterious and 14-year-old Jess cannot figure him out, but with her mother's life at stake, the story tension stays high. Good read for a dark night. ( )
