This week it's been all about the groups and although we'd like to feature them all, here's a selection to start with from our Roskear Reviewers: Sadie wrote a terrific review of Emily Windsnap and the Siren's Secret by Liz Kessler. In this fantastical (and fantastic!) novel, there is a fierce conflict between the humans and the mer-people, and Emily is sent to Brightport by Neptune to bring them together.

"I liked the book for lots of different reasons, but I liked it when they go to Brightport because of how it was set up. I learned that it doesn't matter what sort of personality you've got, for example the mer-people and the humans were split up but never needed to be. I would like to recommend this book as it has lots of imagination and could inspire you to write your own book!"

Another fantastic review from our Roskear Reviewers, this time from Robert who penned an outstanding review of another book by Liz Kessler, North of Nowhere. In this mysterious tale, Mia goes to live with her Grandma in the seaside town where her Granddad went missing.

"I really enjoyed this book because it was really mysterious; my favourite part was the constant messages through the diary. This is a tale like no other. I recommend it to both adults and children over the age of 6. I rate this a 5 star book."

The next group to send in some extraordinary reviews this week were our Millennium RIOT Readers! Continuing the theme of mystery, Ellie P wrote a brilliant review of Love, Lucie by Marita Conlon-McKenna. In this book, Lucie and her big sister Chloe have to come to terms with the death of their mother. (tissues at the ready!)

"I loved this book and especially Lucie because it was lovely when she talked about her feelings and it felt really nice knowing that she still talked to her Mum as if she were there with her … I would recommend this book to teenage readers, especially girls as they will relate to the story. It was quite an easy read but I loved it and give it a big 5/5 stars!"

Similarly mysterious (with added skeletal detectives!), Daniel wrote a magnificent review of Skulduggery Pleasant by Derek Landy. In this series, Skulduggery Pleasant is a skeleton who solves mysteries with the help of his sidekick: twelve year old Stephanie.

"This book was brilliant. I liked Skulduggery because he is a skeleton detective and he is so funny but sometimes very serious … I would recommend this book to readers who like fantasy and adventure because it is packed full of both. It was an easy read but has lots of hard names to remember! I give this 5/5 stars because it is so good!"

This roundup is growing ever more mysterious, as we move on to a delightful review written jointly by site members Lady Abigail and Raindrop of Neil Gaiman's Fortunately, the Milk. This mad story is about a Dad who goes to the shops to buy some milk, but takes an extraordinarily long time... When he returns he tells his children it is because we went on a magical adventure.

First to comment was Lady Abigail:

"My favourite part of this book was when the dad got shot up into a flying saucer and saw big green globby people … I think the dad was making up stories to put imaginative thoughts into the children's heads. I think he was just talking to a friend."

Then Raindrop shared their thoughts:

"I enjoyed this book because it was funny. Professor Steg (the Stegosaurus) does not know the word for emerald yet, so he calls it a green shiny stone; he also calls his hot air balloon a 'floaty-ball person-carrier', and this made me laugh. I don't think the dad was talking to a friend, I think he might just be telling the truth!"

To end this mysterious roundup, it's more mystery (of course!) but with a gothic twist. Site member bedtimestories wrote an excellent appraisal of The Devil in the Corner by Patricia Elliot. To escape her life as a governess in a brutal household, Maud Greenwood seeks refuge in her cousin's home, only to be thwarted by the devil in the corner.

"This is a gorgeously gothic historical tale. I absolutely loved The Devil in the Corner. Personally I enjoy creepy, Victorian-era stories so this was just so enjoyable for me … The characters are very well written and I found all of them mysterious in some way. And the ending was just fantastic! … The way that the book is written makes you familiar with the times and how people were. I really recommend it to young adults and even adults would enjoy it in my opinion! I give it a solid 5 out of 5."

And that's it for this week's roundup – a huge round of applause for our spectacular young critics! If we've included your review in our roundup, please email the Book Elves and we will send you an extra-special bookish treat in the post!
