This is essentially a review of both books of this series. To tell the truth, I almost dnf'd this series when I figured out that the 'apple' they were referring to was actually Apple. Good plot concept, very poor execution. My guess is that Apple had a monopoly on all technology by the time the floods came? Or maybe I missed that explanation. The idea that future generations could look back on our seeming 'worship' of our phones, tablets, computers, etc was a good concept. The actually execution of that throughout the two books was lackluster at best. Also the overuse of the word, 'tick' had my hair standing on end by the middle of the first book. Good lawd-there are plenty of other descriptions to use for portions of time-even in the future.
There were several plot points that I feel were never fully explained and the ending of book two was very rushed and abrupt. All in all, unless you are out of books to read on your tbr shelf-I'd skip this series.
