I seem to have a "thing" for rhyming titles at the moment. Sure it will be a passing fad...!
What attracts you to a book? Is it the title, the blurb, the cover, or a combination of the lot?
For me, the cover draws me in but the blurb is what clinches a sale for me, whether I'm reading on Kindle or a paperback. If I like the premise of the blurb, I will "look inside" a Kindle book or look at the opening page of a paperback. If it seems to deliver, I'll go ahead and buy.
There is no such thing as a foolproof system but this works for me!
Of course, another great hook is reading a book by an author whose works you know you like. I love series novels and my favourite of these has to be Discworld. Each book original and entertaining but there's enough familiarity with the world to make you feel right at home as you continue to enjoy the series.
Whatever you read, enjoy!
