Are You Thinking What I'm Thinking?, 8

Alex and Ava try to figure out if they can read each other's minds in the eighth book of the It Takes Two series! Alex and Ava's older brother Tommy always jokes that the twins can read each other's minds. While it's true that despite their differences Alex and Ava can usually tell what the other is thinking, that doesn't mean they're telepathic. But when the girls choose the same Halloween costume, buy Coach the same birthday present, and show up at school wearing the same outfit, they begin to wonder if Tommy might by right. Can Alex and Ava actually read each other's minds? And if so, how can they use this to their advantage?
