I can't post the full comment I wanted to on the book itself, but I can do it here. Aside from your soulmate concept, the majority of "The Island" is a copy of "One Call Away." I understand your first book in the series said "The Unmatched Records" inspired you, but "The Island" is flat-out copying, especially when I can compare the books side by side and find the same dialogue, wording, and plot progression. I am completely fine with asking to use my concepts to make your own spin on these episodes, but blatantly copying my book, which was published years prior, is not OK.
