This is a sequel to the popular children's book series "Gangsta Granny" by David Walliams, a hugely popular author in the UK. Ben lost his jewel-thief grandmother in the previous book. However, a series of jewel robberies occurs in town, and the culprit looks exactly like his grandmother!? Ben, along with his best friend, sets out to uncover the truth. This is an adventure story filled with humor, laughter, and tears. It's also a recommended book for English learners. I haven't read it much, so I think it's in good condition.
