A word of caution to those thinking of submitting to Flux. I have it on good authority that Flux is renegotiating advances after contracts are signed, and they've done so with several different authors. In most cases I've heard of, Flux is doing this not with their first time authors, but authors publishing either book 2 or 3 with them. Basically, Flux asks for a sequel, an advance is agreed on, and then they send the author a contract. The author signs the contract, turns it in, and then writes the book and turns that in. Flux, on the other hand, will not sign their own contract, and will insist on renegotiating the advance amount after the author has already turned in their book. One can't help but wonder if they're going to quibble over a couple thousand, if there isn't a deeper financial issue at play.
