Thanks to Harry Potter, everything is a series. Here is my ranking with one sentence reviews. If the title is clickable, it will lead you to a full review.
#12. The Jewel– Simple, predictable plot with a whole lot of instalove.
#11. Queen of the Tearling-448 page backstory with uninteresting characters.
#10. Prisoner of Night and Fog-Missed opportunity.
#9. Iron Trial-Fantastic prologue but too many dips in the action and an uninteresting protagonist.
#8. Snow Like Ashes- Convoluted and formulaic.
#7. Midnight Thief-Okay storyline but nothing special.
#6. Young Elites-Interesting plot and characters but too many holes.
#5. Red Queen-Fatal flaws.
#4. Half Bad-Started off well and had interesting characters but it was too preachy and the ending was anti-climactic.
#3. An Ember in the Ashes-Unpredictable, great romances and villains, full of action but the author says it’s a stand alone; however, it can’t be because there’s no ending.
#2. Winner’s Curse-Beautifully written with a lovely forbidden romance.
#1. Kiss of Deception-Slow moving book but it has many layers, it has well-rounded characters, and has great world-building. It’s a novel that requires you to think and make connections. Sorry but this book was too good for one sentence.
