Martin Bridge returns for more slice-of-life adventures in this installment in the widely acclaimed chapter-book series. In Keyboard, Martins summer is off to an unharmonious start when his best friends Alex and Stuart are grounded for accidentally damaging Polar Petes ice-cream truck. Meanwhile, Martins Mother wont stop practicing on her new electronic keyboard -- and shes driving him around the bend. Hes so grumpy that he doesnt feel like helping his friends when they come up with a water-sprinkler-symphony scheme to help pay for their accident. Will Martin change his tune and add some much-needed harmony to his summer? In Rope, Laila Moffat joins the Junior Badgers, much to Martins chagrin. A keener and know-it-all, Laila just wants to win more badges.
