Just Finished the Book Series

I just finished reading The Long Game. I’m glad I finished it because I love this series and Shane and Ilya have grown on me and I love them too. Now that I finished I’m upset there’s no more for another year and the another year for the next season of the show to come out. I love reading and watching tv shows but I hate when they end and there’s no more especially when it’s not the official end. I need more Shane and Ilya. Does anyone else get this way or more specifically feel this way about this series?
