This book is for children of all ages and adults too despite the categorisation: the author's concept when she writes the Henratty Mortimer series of books is to give the parents just as much enjoyment in reading the book to their children who are enjoying listening to the book being read. The author decided to use meerkats when she saw these adorable and very funny creatures on her trip to Newquay Zoo in Cornwall as they made her chuckle so much. There is a character that every individual (child or adult) will love. From series 2 to 5 of Henratty Mortimer books the meerkat always have some sort of mystery to solve, the author never planned it that way but when she took pen to paper the stories seem to unfold and flow almost of their own accord.This book starts to develop the wonderful meerkat characters a lot more especially Henratty Mortimer and Jack Brian, the reader begins to see their competitive nature as they are so alike but do not realise it, whereas the two younger siblings, Lyndi Lou Mortimer and Oscar Brian are the quieter, more focused siblings whom have the same interests and really get on. Henratty and Jack are like two little detectives and love to solve a mystery, especially Jack and no matter the danger Jack has no fear as he loves an adventure. This book shows how clever these two meerkat characters can be when they try to solve this mystery which involves saving the life of Misha Mortimer, Henratty's eldest sister from the evil monster lurking in the woods. The story is depicted by 27 stunning and vivid colour illustrations. The author would love her books to be made into animation as she has many other wonderful animal characters and not just the meerkats that can be found in the third and fourth series of the books and the author has already written four poem picture books based on the other animal characters to publish, such as Poppy The Most Beautiful Worm and Enoch and Escargot's Snail Trail. Again, these books also have an underlying value and are very witty.Other books by Henrietta Defreitas with value:Oscar's Birthday - Share and share alike - 'the green-eyed monster'We Were Only Strawberry Picking - Love thy neighbourSkylark - Keep your friends close but your enemies closerThe Witch's Broth - Love moves in mysterious ways
