Where, oh where did Flo go? Sam N.'s class is back at it again at Geyser Creek Middle School, trying everything they can do to fundraise after their school's sink breaks (and the sink STINKS, too!). They're hoping to use the help of eccentric designer and friend Florence Waters after she helped them on their fountain. But Flo is nowhere to be found! Principal Wally Russ is also short of cash after he sunk all of the school's money for the sink into Rainy-Day Rainwear stocks, which are PLUMMETING after a new technology of irrigation is introduced and endorsed by the newest senator Sue Ergass! But something suspicious is going on, and it's up to Sam N.'s class to save Flo. I encourage anyone to read this comical and super fun book! In the format of different letters sent, newspapers, and illustrations, this book will keep you turning pages! Also, I loved how every single name is a clever play on words... it's so fun to figure them all out! I recommend this book for middle grades, and I would rate it a 4/5 stars!
