The Cold and Hot Winter — Johanna Hurwitz

Friends...forever?

Bolivia has been best buddies with Derek and Rory ever since last summer when she was visiting next door. This winter she's back again for more adventure. But first -- presents! Bolivia comes up with a great way to make Christmas last a little bit longer. They all wrap fun things like Bolivia's brand new Swiss army knife, or even boring things like a can opener, and then hide them around the house.

But Bolivia's knife disappears. Then Derek's hamster disappears, too! The three friends start accusing one another of stealing. Someone had better explain fast or else their friendship is off!
