As seen among these pages, there used to be big books called "Sonic Annuals". There has not been a UK area Sonic book released in ages though, annual or otherwise. However in 2013/2014 "Pedigree Books" is stepping up and creating another Sonic annual book.
This one though, will be different from all of the others, not just because it is modern but because it is likely to be the second actual "Sonic AR / Augmented Reality" item ever made. This means, that with a tablet, smart phone or other portable screen device, you can use its camera to "look" at QR code symbols (or something similar) and then get added content like extra information, animations or mini games. Look at the dot on the cover there, it's showing that you can use it to color in a picture in the book....virtually!
The "official" stamp up there is the real deal, as whoever was licensed to do annuals seems to have passed them on to a worthy successor. Want to order / pre order it? You can at The Book Depository . Photo & info discovered by the Sonic Stadium.

With actual augmented reality technology, this'll really be a book to get, especially because it's the first one to have such a thing, and only the 2nd Sonic item to ever use it. Books are also generally reasonably priced & easy enough to get. Review pending actual release.

"Sonic the Story". It's a picture book with text and the titular story is told by Tails, with occasional prompts from Sonic along the lines of "Get on with the story!" and "This is all getting mega-technical. Can't you hurry up and get to the me-being-a-super-hero part of the story?". The story is indeed the retelling of the creation of Robotnik from Dr Kintobor and speeds through some of the Sonic 1 levels.
The back says: "Sonic the Hedgehog and Ladbybird join forces to bring you some fast, furious, frantic and fun-filled radical action! "Wise up, chill out and make sure you don't miss out on these mega-awesome books:

"Adventure Gamebook 1, Adventure Gamebook 2, Puzzle Book 1, Puzzle Book 2, Where's Sonic?, The Invisible Robotnik Robotnik's Oil, & Colouring Poster Book"
