Plenty of fun for Gilbert fans!
Format: Hardcover
As in previous books in the series, Gilbert the Goblin complains about the problems he sees with Valentine's Day, what he calls 'mushy malarkey'. Young readers who don't care for the holiday will find much to relate to in the book. Although, Gilbert's complaints seem a tad trifling. Coconut chocolates are 'Blech'. He seems to have a special issue with the cupid's 'perfect', 'beautiful', and 'luxurious' hair. When Gilbert faces off with a group of cupids, he just barely manages to escape their love arrows, or so he thinks until he backs into a cactus in his own yard and believes he has been pricked by one such love arrow. He then becomes a goblin full of love. He loves his spells, his potions, even himself, but not coconut chocolates. He even welcomes his friends over to celebrate before bidding his pet sock slugs a fond goodnight. Good thing the love spell wears off. This funny book follows the pattern of the previous five books, but the addition of adorable cupids as well as Gilbert's beloved cactuses and pet sock slugs provides plenty of freshness as Gilbert once again (reluctantly) joins in the festivities. Plenty of fun for young fans of the series.

Best way to explore Paris
Format: Paperback
This book is awesome! I enjoyed reading it just as much as my kids did! I love the layout and the way that the book assigns the kids to be secret agents, but defers to the case officers (parents) for the final say. We were in Paris for 1 week and although the weather was less than cooperative, we were able to capture our 100 points and award our 4yo and 7yo their secret agent certificates. I love the fact that you can work on this book in any order and do as little or as much as you want at each attraction. The price was awesome and worth every penny. My 7yo particularly enjoyed the challenges at the Musee D'Orsay and the Louvre and it was a great way to keep those visits focused and entertaining for the kids. My 4yo was a little young to stay engaged with every "mission", but the activities were easy enough that she could help (ex. finding a winter scene in the Musee D'Orsay). I loved that this book engaged the kids but didn't detract from any of our visits (we didn't feel like we had to go "out of our way" to find anything). The only disappointment was that they didn't include Versailles and Sainte Chappelle. I have not only recommended this book to all my of friends traveling to Paris (honestly with or without kids), but I have also already purchased the similar books for London, New York, and Washington DC. Can't wait to see what other cities they add!

Afun way to see Paris as a kid
Format: Paperback
Great way to have kids really look at the sights of Paris. Encourages group or single competition to do each activity. Lots of visual clues.
