Leeli, have you ever read The Guardian Herd books? It's a fantasy series about pegasi by Jennifer Lynn Alvarez and it's reaallly good.

Also, The Inquisitor's Tale by Adam Gidwitz is a really good book. It's sort of a cross between historical fiction and fantasy, set in medieval France. It's about three children with supernatural powers. William is very tall and super strong, Jacob has these sort of healing powers, and Jeanne sees glimpses of the future. It's very entertaining, and interesting and I'm pretty sure it won the Newbery one year. 

Oh! And the Foxcraft trilogy is good. It's about foxes that can do their own magic called Foxcraft. Some of the things they can do are slimmering, which is where a fox makes the illusion of invisibility to sneak up on prey or avoid enemies, and wa'akkir, which is shapeshifting into another canine animal, or cub of Canista, as they say in the books.

Annnd  Red Falcons of Tremoine, by Hendry Peart, which is a historical fiction set in medieval England about a 15-year-old boy named Leo who is heir to both the estate of Warlock, and Tremoine, whose families have had a blood feud of sorts for a long time.

Hope those keep you occupied for a while! :) 

Not to be rude, but Leafmist had a lot of great recommendations on their thread and there are a ton all over BaB. Here's a few of my favorites just in case you aren't finding the ones for you. (And honestly, just because giving people book recommendations is one of my favorite things.)

Sci fi

- A Wrinkle In Time

- The Giver

- The Choas Walking Trilogy

Fantasy

- Septimus Heap Series

- The Lunar Chronicles

- The Sister's Grimm

Mystery

- The Boundless

- A Series Of Unfortunate Events

- The Westing Game

Realistic Fiction

- The Red Pencil by Andrea Davis Pinkney

- Wonderstruck by Brian Selsnick

- Because Of Mr. Terupt by Rob Buyea 

I recommend the Theodosia Throckmorton series. It's about a girl who can sense Egyptian curses on artifacts in her parents' museum, and she's trying to remove the curses without harming her family, her country, or the secret society she joins. Then this other secret society, an evil one, tries to kidnap her.

That's not a very good summary, but whatever. 

A wrinkle in time

The glass children

Murder Most Unladylike

The HTTYD series (it may be a little bit young for you, but in my opinion, no one is too old for the How to Train Your Dragon Books)

Miss Peregruins Home for Pecuilar Children 

hi! i don't know how old you are so i'm not sure what age level of reading you enjoy, but! if you haven't read jandy nelson's work yet, i highly highly recommend. it's realistic fiction and it's so good! i can't do summaries very well without spoilers, but you should look them up! they're so good. if you have read them i also recommend aristotle and dante discover the secrets of the universe and the catastrophic history of you and me. as far as i'm aware they aren't as popular but they are both incredible as well. hope i could help!

Dodger by Terry Pratchett

A young tosher (person who makes a living in the sewers) living in Victorian London sees a despicable act one foggy night and gets launched into a world of reporters, spies, intruige- and becomes a hero totally by accident.

I would recommended the five kingdoms series.  

PS the fifth one is not out yet so you might want to wait until it's out

Oh, I’m listening to an audio book, called, The Night Gardener. It’s a child's thriller. It’s super good!! And it’s a mystery too.
