Harrow the Ninth (The Locked Tomb Series Book 2)

Although I did not enjoy the sequel as much as the first book in the series, this is also a very good read! You will spend a lot of time wondering just wtf is going on, but the writing and plotting are superb. I cannot wait to continue the series with Nona and eventually Alecto. Once you pick this one up, you won't want to ever stop reading about the Nine Houses and the Locked Tomb

Made me confused for quite some time while reading, but it was worth it in the end
