I, unfortunately, experienced that sickly disappointed feeling when you pay $4 for a book, download it and then see that it say that there is an hour and a half left in the reading. I can see now why you put the first three books as an omnibus. It's the only way to make people think that they are reading a real book series.
Don't get me wrong, I loved the story and the writing was ok. But I really should not be able to read 3 books in your series in one afternoon.
I will not be purchasing the rest of the series, even though I would love to read them, because I am not willing to pay $25 for a series that I will likely read in 2 days.
