I'm going to add some more stuff in addition to my Netgalley review.
Something I enjoy in books is when they make a reader want to learn about things he/she read in the book. If it mentions something historical, scientific, literary, philosophical or fantastical and the reader can't wait to look up more information. I found both The Library of the Dead and Our Lady of Mysterious Ailments to be these kinds of book. Roja, the protagonist, is so curious about the world and her is contagious. I hope other readers find her knowledge intriguing, too.
Now for the rest:
I sure do enjoy the personality of Roja, the protagonist of Our Lady of Mysterious Ailments and of The Library of the Dead. She has this foul mouth but a tremendous intellect, way past your average 15-year-old or 65-year-old for that matter. She knows history, philosophy, science; she knows Occam's Razor for heaven's sake. I wish I knew half the stuff Roja knows. (I'm jealous of a fictional character. Sad.) I admit I miss her ghost talking and playing the mbira to help understand the ghosts. Even though her magic is now beyond ghost talking, I liked the personalities of the various ghosts and the way they always said, "Booga Wooga!" (Disclaimer: As a child I used to play ghost--I was, um, that kind of child, and I always said, "Booga Wooga!" Who knew I could speak ghost when I was a mere tyke.) Maybe in future books we'll see more ghost talking. Roja, her family, her friends, and her boss are likeable. The badies are nasty, foul, and super unlikeable. And, I got to learn some super cool Scottish phrases and terms. Now I'm going around saying "I dinnae know that." Thanks to Netgalley and Tor for allowing me to read and review an eARC of Our Lady of Mysterious Ailments.
