Brave and moving

What a perfect Christmas story! I finished it a few days ago and I'm still thinking about the characters, how well-done the story was, and how the author managed to make me feel like I was right there in Illinois with Murphy as we followed her holiday adventures. Murphy just wants to pass the accounting class she's struggling in so that she can join her best friend, Kat, at the college they've always dreamed of attending. Kat is already there, living her best life, while Murphy had to stay behind in their small hometown. Murphy has made the best of a bad situation, becoming a marketing sensation for the coffee shop she works at, but she misses Kat and all the plans they had. When Kat's long-awaited visit home for the holidays takes an unexpected turn--she's brought her boyfriend home with her--Murphy feels even worse than before, until she runs into a former classmate who has a plan that will help them both. Ellie needs Murphy to pretend to be her girlfriend for a family dinner. In return, if Murphy can impress Ellie's mom, who happens to be Kat's accounting professor at community college, maybe Murphy will pass that difficult class after all. The only problem? The girls didn't expect for real feelings for form. And Murphy didn't count on having fights with Kat. Or for everything to get a whole lot more complicated. I just loved this book. Murphy is someone I think a lot of queer girls will identify with and my heart ached for her at more than one point. Meanwhile, Ellie is a likeable enough love interest with a story of her own. I felt the very real chemistry between them and the pining, too. It was clear right from the start that there could be something there, if only they were both brave enough to take the chance right in front of them. At its core a story about growing up, navigating the dynamics of a changing friendship, and accepting unexpected blessings, I'll Get Back to You is a really sweet and moving holiday story.
