I started writing down a thought of an idea "What if I found 'my' werewolf mate." I had written only a couple chapters of Wolf Tech 1 (and they looked much different... without any names of the characters...) and had send a copy to another author, who I had been chatting with and doing some edits for his stories.
Posting it up on Wattpad, Brian then posted a shout out to his readers. I then had a fair number of readers start demanding more content. Eventually, I finished Wolf Tech 1: New Beginning and started on the second book before I realised it, which is why they are in the same book on the Wattpad site.
I finally have arranged to have the edited books as published books.
