Meant To Be by Lauren Morrill

From Goodreads:
Meant to be or not meant to be . . . that is the question.

It's one thing to fall head over heels into a puddle of hazelnut coffee, and quite another to fall for the—gasp—wrong guy. Straight-A junior Julia may be accident prone, but she's queen of following rules and being prepared. That's why she keeps a pencil sharpener in her purse and a pocket Shakespeare in her, well, pocket. And that's also why she's chosen Mark Bixford, her childhood crush, as her MTB ("meant to be").

But this spring break, Julia's rules are about to get defenestrated (SAT word: to be thrown from a window) when she's partnered with her personal nemesis, class-clown Jason, on a school trip to London. After one wild party, Julia starts receiving romantic texts . . . from an unknown number! Jason promises to help discover the identity of her mysterious new suitor if she agrees to break a few rules along the way. And thus begins a wild goose chase through London, leading Julia closer and closer to the biggest surprise of all: true love.

From Misty:
So. Stinking. Cute. Untilllll...Julia got annoying, un-characteristic, and started making a string of terrible decisions, each one worse than the last. But don't I always say something snarky and critical like that? The real truth is I laughed through the whole book. I HIGHLIGHTED the hilarious parts. Yes, it's true. I haven't highlighted in a fiction book since...well, I'm not going to admit to that level of nerdiness.

Ultra-organized Julia has everything planned out, including life with her MTB (meant to be), Mark--who has no idea. Stuck with Jason, the reckless reprobate, as her tour "buddy," (you know, the buddy system), Julia is sure he's going to ruin her trip. But the only thing he ruins is her idea of MTB--because maybe she's meant to be with him.

My favorite kind of book. I was just drowning in the cuteness.
