Not-Quite Human — a series by Vincent Berg

Al and Betty have peculiar skills which set them apart, and which leads them to search for others like them. As they discover who they might be, they become alienated from friends, family and humanity in general. They must discover who they are and where they belong, as there no room for them in their world. Between walking into disasters, ungrateful rescues and government agents tracking their every movement, they're searching for a way out and a way home, wherever that might be.
