In this seventh installment in the Just Grace series, any day now Grace's best friend in the whole world, Mimi, is going to be getting a brand-new sister. Grace is really excited, plus nervous, plus worried, plus happy all mixed together. But both Grace and Mimi are in for a surprise when they find out that Mimi's family is not adopting a brand-new sister-and instead she is getting a brand-new brother. (Oh, brother!) And to heighten the excitement even further, Grace is in for another big surprise!
