Currently reading Fables in trade form, and I'm up to volume 4 (no spoilers please). At what point does the spin off Jack of Fables start and other than the crossover issues in Fables volume 13, is it essential reading?

Also, at what point should the Cinderella spin-offs be read?

Thanks

You don't need to read either. I've read both. Their O.K., but not that great. Read them for enjoyment if you want. Fairest looks like a must read though.
