If you couldn't quite follow the events in Gideon the Ninth and found the book confusing, this one is definitely not for you.

Harrow the Ninth continues the Locked Tomb series where Gideon the Ninth left off. It is a complete mindfuck however (excuse my language) and with every page I was delightedly wondering "ok, what unexpected event or information will come next?"

If you liked the first one, this continuation will make you like the series even more.
