A Soul Above the Rest (Avengers Soulmate Story)

In a world where people have their soulmates mark/s on their body, Flora has found herself in a bit of a pickle with a soulmark number far larger than anyone has ever seen.
Who could all these people be?

Meanwhile the Avengers has decided that they have to take drastic measurements, if they want to find their soulmate. They've been waiting for long, and none of them will rest until their soulmate is found.
Even if it means leaving The States, and ignoring Fury and his paranoia for the black, smoky clouds.

This is book 1 (Book 2 is out but discontinued)
