In a world where knowledge is power, the library is the greatest weapon of them all.

My necromancy-practising murderers never expected me to rise again.

I was just the latest in a long line of gullible sacrifices to ensure their continued control over the Arcanaeum, so it shocked everyone when I woke up as a ghost and kicked them out.

For centuries now, I’ve faithfully carried out my self-appointed duties as the Librarian. I keep the vast halls of magical knowledge organised, fight the mad whims of the sentient—and interfering—building, and deal with the incessant demands of our patrons.

I have all the books and solitude I could ever want, the ability to redecorate whenever I get bored, and I can banish arcanists who refuse to follow my rules.

But the Arcanaeum has started acting out, especially when it comes to six particular patrons, all of whom want something from me.

Jasper and Dakari need my protection, but Pierce isn’t above threatening me ensure I give them both up. There’s no rule Galileo and North won’t break to get into the secret vault. And then there’s Lambert, who seems to exist for no reason other than to vex me with his smiles and hugging.

Inconvenient, given that every time they touch me, my ghostly body cracks and breaks like glass.

To keep the Arcanaeum safe, I might just have to put my trust in all of them, but what if the cost of the building’s safety is my destruction?

I called, he came, and now we'll both pay the price.

Earning the allegiance of the seelie royals was meant to be the easy part of my pilgrimage. Instead, the Spring Queen broke my Guard with her petty games, and then the Summer King imprisoned them. He tried to murder me, and would have succeeded… if not for Bram.

Now wounded, and with nowhere else to turn, I have to put my trust in the one male who's more dangerous to me than any other—Caed. I'll do anything to rescue my Guard, even if it means risking their anger and giving him another chance.

Even if we manage to free them, the rifts between my mates are almost as deep as the ones tearing the fae realm apart. If I can't stop the infighting, master my magic, and claim my place as Nicnevin, then the Fomorians have already won.
