It seems that so many authors lately are simply "outgrowing" their own series. Perhaps I'm wrong and this book will be released...someday. Sadly, I probably won't read it. I will no longer waste my time with a series until it has completely been finished due to the inability of some authors to stick with and finish their series.
When you write a book, how about you know where you are going with it. Plot the entire thing out. Not just the first book. Know everything about your story and the characters then when writing fill in the little stuff that's important. If not make just standalones. Finish your stories. Don't just have an idea put out the beginning, get a following, then fall of the face of the earth. She got intimidated by the following and was scared to write, it seems. At least going by her last post about it on FB. She didn't want it to revolve around the romance like the first one did, so she didn't want to disappoint anyone, is what she said. I can understand that but delete Tempus from AMAZON and Goodreads since you completely abandoned it, so people don't come across it.
Its better than Arcanus by Ali K Eke, This book was a great read. There is another book called "Arcanus" by another author, but this one is far superior.
