I have written 7 Novellas featuring 7 different characters. Each story takes place in the same city. Each story is a mystery where each character solves a murder or some kind of crime in this city. I've asked quite a few well known agents if they were interested in a collection of crime novellas and ive gotten a "yes" but only if they were "connected" to be marketed as a novel. How does one go about connecting these 7 stories together? The only thing i have so far that's an immediate connection is time/setting. The 7 crimes don't connect but the characters solving those crimes do connect in ways. Some have immediate connection to others while some doesn't until later on in the series. (yes, i plan to make it a series) For example: One character is the long lost sibiling of another character. Its not revealed right away. But it will be down the line. Another character will be the mother of another character who thought his mother abandoned him after birth. Again, not revealed right away. Here are a few connections the characters have also: They all attend this institution that trains them to fight and solve crimes. They all attend events and ceremonies together. They are connected through friends and families. (ex: MC 1 best friend is dating MC 2. But MC 1 doesn't meet nor interact with MC 2) They all compete in the same sporting competition. Is time/setting enough to connect these stories to be marketed off as a novel?
