Well, That Was Awkward by Rachel Vail

Grades 3-5

Gracie has a huge crush on A.J., but is bummed when she finds out he’s into her best friend, Sienna. Of course she’s happy for Sienna, and makes it her mission to help Sienna write the best texts, and write to A.J. as if she is Sienna. She has no problem being Sienna’s sidekick…well, at least she’s trying.
