I just read this book, spent all afternoon and night reading it. It's almost 2AM and I just finished. However, the book ends very abruptly with no mention of book 2. Is there a book 2? If so, I'm assuming it has already been submitted to the publisher (typically for an unknown author writing a series, the publisher would require the whole series to be complete before publishing), and so there should already be a date set to release it? So, when will book #2 be released? Thank you.
