Kids love the newest “Worst” tale-
Format: Hardcover
Kids will love this next book in The Worst series. Awesome, fun, colorful illustrations in this tale with Gilbert the Goblin trying to escape cupids and valentines. Instead of candy for Valentine’s Day give the gift of this book. My students love when Alex Willan has a new book out and are loving this one.

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.
