Project: Romantic is an excellent anthology. In fact, all of AdHouse's
Project books are great, but this is the only one still available. It's also my favorite of the series.
Along the lines of
Put the Book Back on the Shelf, there's a new Tori Amos-inspired book from Image called
Comic Book Tattoo. I haven't read it yet, but I've heard great things about it, making me even curious although I'm not super-familiar with Amos's music.
Papercutter is probably my favorite anthology series being published. They are published in smaller issues with only 3-4 contributers each issue, so it's a lot smaller than
Flight, but each issue is fantastic. You can get those from
Tugboat Press.
