Yes, Marius is right. I named the book Exploring Lift at the start
and it was announced as such.
After a bit of thought, APress aligned it with the rest of their
titles The Definitive Guide to <subject>.
I imagine that in time, the previous name will be marked as invalid
and Amazon et al. will drop the listing.
We're not attempting to confuse people, it was just a series of
events.
