As per usual, I have to plug my all-time favorite book, The Phantom Tollbooth. Barnes & Noble has a special 50th anniversary edition, so keep your eyes peeled for that.
I also have to plug my friend thesylverlining‘s book, Chameleon Moon. It’s a dystopian superhero novel with lots of heart and an entire cast of MOGAI people. It’s really good, and I will not stop until everyone on Earth has read it. (And then we can start with the rest of the universe…)
The Lunar Chronicles series has been making me very happy recently, so I also recommend the books in that series - Cinder, Scarlet, Cress, Fairest, and the upcoming release of Winter. (Winter won’t be out for a while yet…but I can dream…)
Any of Tamora Pierce’s Tortall books would be good if you’re into fantasy. The first books come in sets of four - Song of the Lioness, The Immortals, and Protector of the Small. Then you have Daughter of the Lioness (duology) and Provost’s Dogs (trilogy). But don’t think you have to read the first sets to understand the later sets. My favorite of the entire verse so far has been Protector of the Small, and it was the first one I read.
If you want something a bit more comedic, Hyperbole and a Half might work. It’s by Allie Brosh, the person who wrote the
infamous blog. You’ll laugh. You’ll cry. It’ll move you, Bob.
And finally, I recommend the Harper Connelly Mysteries by Charlaine Harris. They’re about a woman (Harper) who has the ability to detect dead bodies and see how that person died. They’re really unique books and very good.
I hope these help you get started. I have tons more where they came from, so don’t hesitate to come back if you want more. :)
