I hadn’t even realised it was a series! Maybe I should check out the next one.I have read the first and second and really enjoyed them!
I have the third, finale, but haven't read it yet.
For me it is an odd series, it is one that I have to convince myself to read the next book but when I do I love it! So I don't know why I am so reluctant to read them.
The concept is different to anything else I have read. And the style of writing is very different to my normal reads (thrillers or YA)
ETA I would probably read the first one and if you don't get on with it don't worry about the rest of the series. The first book works OK as a standalone.
I know what you mean about having to convince yourself to read the next in series despite enjoying them. I did the same with the Miss Peregrine series and the Asylum series (think I got to book 3 and have yet to start it).
