90s book need id may have sleeping dragon in title

the book is about random people being transported to an alternate world. in the instance of the book it's a neighborhood that transported.

when the people come out side after they realize they been transported, they are met by a guy peddling ice cream and he tells them some info.

if i remember correctly they are bought to this place as food for powerful beings of magic, each time people are transported 1 person in the group is imbued with powers that make them strong as the beings wanting to feed on them.

some of the members of neighborhood escape and link up with a militia from the 20s or earlier suggesting the people are taken from multiple time lines.
