If you only have time for a Top 5:
1. This Savage Song by Victoria Schwab (Monsters of Verity 1)
This is perhaps my favourite book of 2016. It's both a re-interpretation of the Romeo and Juliet trope, as well as a powerful look at what makes someone human/what makes someone a monster. I love the characters; I love the world. It's a triumphant return to YA for Schwab.
One of the best books I read this year, Yoon has written an intricate story of two people and their lives and love and how it echoes out into everyone they meet and encounter. It's got an incredible voice for each of its narrators, and
3. Crooked Kingdoms by Leigh Bardugo (Six of Crows 2)
I love the characters in Bardugo's Kettledam books, and given that this was a duology means tightly executed arcs. They're heist books with complicated and diverse casts, and the world is built with an ease that belies how vast and complex it is.
4. Spindle by E.K. Johnston (A Thousand Nights 2)
Thoughts about it here
5. The Raven King by Maggie Stiefvater (The Raven Cycle Finale)
Thoughts on it here
If you've got time, here are some other great ones I read in 2016:
Behold the Bones by Natalie C Parker (Beware the Wild companion)
Thoughts on it here.
A Gathering of Shadows by V.E. Schwab (A Darker Shade of Magic 2)
AGoS was more than a middle book in a trilogy—it's better and more engaging than ADSoM, but it also perfectly sets up the finale. (A CONJURING OF LIGHT is out in February.)
Exit Pursued By A Bear by E.K. Johnston
I read it n 2015, but it came out this year. Johnston's first contemporary title is a powerful reimagining of A Winter's Tale. It features what I very much love about her work: People taking care of each other and small towns/rural settings being treated as important and vibrant as cities. It's a book about how important it is to write the world the way it should and can be.
Places No One Knows by Brenna Yovanoff
I'm not sure I would have enjoyed this book as much as I did had I read it at any other time, but Yovanoff's lyrical prose is at its best and the magical/unusual element is so subtle that this might as well be contemporary.
Vicious by V.E. Schwab (2013)
A look at heroes and villains, this dark novel really gets superheroes.
Heroine Complex by Sarah Kuhn
This fun book about superheroes manages to also say important things about friendships. Led by a diverse cast, it's a romance with a little bit more to it.
Necessity by Jo Walton (Thessaly 3)
Walton's finale to her Thessaly trilogy makes up for the somewhat meandering second book, and brings everything together in a meaningful way.
A Little Taste of Poison by R.J. Anderson (Uncommon Magic 2)
Anderson has written two stupendous magical mystery books with delightful characters in an early 20th Century setting. They are all the best bits of Dianna Wynne Jones.
Swan Riders by Erin Bow (Prisoners of Peace 2)
Bow has written an incredible companion to The Scorpion Rules that explores identity and humanity.
The Star-Touched Queen by Roshani Chokshi
Lyrical with influences from Indian and Greek lore, this lush fantasy story spends time building its world and intrigue.
Furthermore by Tahereh Mafi
A colourful adventure through a magical land of Mafi's own creation, Furthermore is in turns delightful and terrifying. A magical middle grade.
The Dream Quest of Vilette Boe by Kij Johnson (Tor.com novella)
A reimagining/sequel of The Dream Quest of the Unknown Kadat, Johnson provides a feminist view of Lovecraft.
The Female of the Species by Mindy McGinnis
A feminist Dexter, McGinnis writes a great friendship between a set of characters. Again a smalltown setting. (I'm sure Netflix will make an adaptation of it soon enough.)
Every Heart a Doorway by Sean McGuire (Wayward Children 1)
Interesting characters, excellent concept. It's a little thinly written, but if it is going to be an ongoing series then perhaps the author will flesh things out in multiple shorter volumes instead of a single story.
Pax by Sara Pennypacker
This was not what I was expecting at all, despite being warned by several people that it wasn't going to be what I was expecting. What could be an animal in the wild adventure becomes a contemplation of human nature, world, and love.
Ahsoka by E.K. Johnston
This is the first Star Wars tie-in I've ever read, and I had no familiarity with The Clone Wars beyond a brief introduction from friends. As a result, there are things that I understood would've meant more to another reader. But there is enough introduction that a new reader will feel intrigued and want to learn more. Also, Ahsoka Tano is the best Jedi ever.
A Darkly Beating Heart by Lindsay Smith
This book conveys the experience of being a Japanese American in Japan (please note it's not an ownvoices title.) It's seeped with the sense of being in Japan, but it's dark and angry in a way that Western stories about Japan don't tend to be.
Fate of Flames (Effigies 1) by Sarah Raughley
This book is heavily influenced by Avatar the Last Airbender, Pacific Rim, and Sailormoon. It's great to read a diverse cast in a book that commits to being over the top. It's very well-paced and the fight scenes are intensely visual.
Searching for John Hughes by Jason Diamond
I don't read a lot of nonfiction, but Diamond has an interesting tale of how Hughes movies and their settings in and around where he grew up influenced his life. Like many of Hughes movies it's a tale of what someone went through and had to overcome, and how they ended up all right.
