The fourth and final installment in the spellbinding series from the irrepressible, #1 New York Times bestselling author Maggie Stiefvater.

All her life, Blue has been warned that she will cause her true love's death. She doesn't believe in true love and never thought this would be a problem, but as her life becomes caught up in the strange and sinister world of the Raven Boys, she's not so sure anymore.

I wish you all a series like this.

It doesn't have to be this one, but I hope it's this one.

I wish you a series that mirrors not your life, but the way you feel about your life. I wish you a series where you feel every word like it's yours - not just meant for you but plucked from a subconscious you only glimpsed in yourself, but never paused to consider until it was there, on the page. I wish you a series where every character is a part of you - not because they've grown on you, but because they grew out of you.

I wish you not a series that improves with each installment, but a series which starts out with the best version of itself, and remains consistent throughout. I wish for its final line to be its opening line, and for its opening line to be its final line.

I wish you a series you're terrified to recommend to others, because it's akin to putting your soul in their hands and asking them to judge it.

I wish you a series which you'll read through a hazy blur of tears and still feel content and complete and infinitely grateful that you've found it.

I wish you a series you dread to finish and declare over, only to remember how deep the story goes, and how much more there is left to discover between the lines. I wish you a series with subtext and layers and parallels and archetypes which will never, ever make it truly over. I wish you a treasure hunt through a series where the treasure is in every word.

I really, really wish you a series like this.

And it doesn't have to be this one. But I hope it's this one.
