A Publishers Weekly Best Book of 2020 Nominated for the Carnegie Medal Sonia and I have a lot in common. Our parents are divorced. Our dads are gay. We both love barbecue potato chips. But she is different from me in at least one way: you canāt tell how sheās feeling just by looking at her. At all. When Beaās dad and his wonderful partner, Jesse, decide to marry, it looks as if Beaās biggest wish is coming true: sheās finally (finally!) going to have a sister. Theyāre both ten. Theyāre both in fifth grade. Though theyāve never met, Bea knows that she and Sonia will be perfect sisters. Just like sisters anywhere, Bea thinks. But as the wedding day approaches, Bea makes discoveries that lead her to a possibly disastrous choice. Making a new family brings questions, surprises, and joy in this brilliant modern classic by Newbery Medalist Rebecca Stead.
