I found this topic really hard because there are a lot of types of swooning. There are books that make you swoon that are cute and light, sexy swoony, and of just plain swoony boys. So my list is a combination of all the different types of swoon.
1 The Scorpio Races by Maggie Stiefvater
So many things in this book made me swoon and it wasn't just Sean Kendrick (although he helped). I also swooned over the island, Puck's family, and the entire race!
2 Endless Knight by Kresley Cole (Ok, anything by Kresley Cole)
I was introduced to Kresley Cole last year and have since read most of the books she's written. Her books a definitely an example of sexy swooning.
3 Anna and the French Kiss by Stephanie Perkins
This is cute and light and swoon perfection *sigh* Etienne!
4 The Summer Series by CJ Duggan
I didn't want to pick just one book in this series so I picked them all! This is the perfect summer, beachy, happily ever after series.
5 Meant To Be by Lauren Morrill
When I first read this prompt I immediately thought of Meant to Be! It is the perfect example of cute and light and oh so swoony.
6 The Indigo Spell by Richelle Mead
Actually, Adrian Ivashkov swooning should just have it's own section! I loved him in Vampire Academy and adore him in Bloodlines.
7 The Iron Knight by Julie Kagawa
I wasn't Ash's biggest fan until this book. Having a story written from his POV demonstrated just how much he cared for Megan and that made me swoon.
8 Unravel Me by Tahereh Mafi
This definitely falls in the category of sexy swooning. I am firmly on Team Warner.
9 Clockwork Prince by Cassandra Clare
Oh Jem. I loved his inner turmoil with yin feng, and his devotion to Tessa. Very swoony.
10 Shadow and Bone by Leigh Bardugo
Do you like your swoons to be a little darker and more devious? Shadow and Bone is for you!
