Neil Gaiman alternatives

I asked this in another sub and I think it was both the wrong place and I made it too confusing. So let's try here.

I'm looking for books that could be alternatives to Neil Gaiman's books. Think of it this way:

If you enjoyed American Gods, then you'll like…"

If you enjoyed Neverwhere, then you'll like…"

If you enjoyed Stardust, then you'll love…"

Basically, just pick a Neil Gaiman book and suggest another book by a different author that you think could be a good substitute for it.

Thanks
