After thoroughly enjoying Portofino,re-reading and loving it even more the 2nd time around, recommending it to my book club ,etc, I couldn't wait to read Saving Grandma. Altho it was funny at times, I found the humor very 'dark". All Calvin really cared about was sex-with his "little thing", with Jennifer' and helping his friend. Come on!!!I can't picture that one. Grandma was not one bit believeable-too one dimensional, Dad was in a REALLY bad mood, for sure, and Mom was losing it as well. Sorry, but I won"t be recommending this book!
