I absolutely loved this book . a sequel involving the city they build would be awesome to read . I've enjoyed all 5 books that you've wrote on here and can't wait for your next story .
Haha, pretty thanks Brandy!! Every book of this series will be a stand alone, however the city will make its appearances in the future (probably in the third book though), next is being written and we will visit the demon island!
Hope you enjoy it too when it comes out! (●>ω<)ノ゙
