'Lucinda's Secret' is the third book in the Spiderwick Chronicles - continuing from where Book 2 -'The Seeing Stone' left off.
The Grace children are in more danger than ever. Thimbletack their house-boggart has fallen out with nine year-old-Jared because he refuses to give him Arthur Spiderwick's old book containing the truth about the invisible faerie world - only now, it isn't invisible to the Grace kids any longer. A hobgoblin spat in their eyes, giving them 'the sight,' and now they see magical creatures that are invisible to their mother and everyone else. This is perhaps as well, as Jared's twin brother Simon is looking after an enormous injured griffin!
The old house that the Grace family live in belongs to their Great Aunt Lucinda - locked away in an insane asylum for refusing food and claiming she is fed by faeries. Jared realizes that their mad relative isn't perhaps as insane as people think - so he, Simon and Mallory visit her, to ask her advice about what they should do with the Field Guide. But when they return home they are in for an unpleasant surprise. This time their adventure involves a phooka, a unicorn and some beautiful yet sinister elves.
These little books are like something from a bygone era. The writing is a delight - but it is the illustrations that make them truly special. They are amply illustrated with fabulous 'Arthur Rackham' style pictures that will delight children from 8 to 80.
This book is the third in a series of five - about the strange, magical, and decidedly dangerous inhabitants of the invisible faerie world that surrounds us. The Spiderwick Chronicles continue with: Book 4 - 'The Ironwood Tree.'
