Death: At Death's Door isn't written by Neil Gaiman. It's one of the spinoff novels, focusing mainly on death but also on Despair and Delirium. It's a manga, with manga style rather than any of the more typical styles for the series, which just looks odd. It's very very cute, but it looks odd. It suits Delirium, and mischievous-looking Desire is pretty awesome, but it looks weird on Destiny, Despair and Dream. Death pulls it off okay, she's cute as a button anyway, but... It still looks kind of weird.
The plot is based on Season of Mists, basically. It's just from a slightly different perspective and a lot of the scenes are repeated in the manga style. It sort of makes sense if you're reading it a long time after you've read the main series, but if you've read Season of Mists recently, it seems really pointless.
Plot-wise and character-wise, there really isn't much new. Death is a bit more specific about her job, and there's a party in Death's realm, but other than that, there's really nothing special. Get it if you're mad on collecting things, borrow it if you're not and you're curious, and don't bother if your eyebrows are raised right now. It is exactly as cutesy and lacking in substance as you're thinking.
