'Trouble Never Sleeps' is the final book of 'Trouble is a Friend of Mine' trilogy. I love that book for soo many reasons! First of all, the plot is very gripping with lots of turns of action. Secondly, you will be friends with all the characters in an instant. Zoe and Digby will make you not only laugh out loud but also swoon a lot! I love the exchanges between the characters -some hilarious quotations are worth remembering! What I value most about this book is the fact that it's unpredictable, full of intelligent wit and it also has a romantic thread - Zoe and Digby's relationship is a bit complicated since Digby tends to disappear a lot, but it evolves through three books to give readers what they deserve in the last final book.
