Without having looked at your book... I’d say write it regardless.
This is some advice that I got from a literary agent at a writing conference I attended, just this past weekend: You should write something that you enjoy writing, rather than worrying about whether it is a story that readers are currently interested in or have an appetite for. Generally, any idea can be a good idea, if executed well. If you are enjoying writing your story, your passion will shine through and readers will enjoy it.
That being said, I will have a look at your book ideas when I have more time, later this week :)
