  In this brief invited review, I will attempt to summarise some of the key
areas of interest in the study of central stars of planetary nebulae which
(probably) won't be covered by other speakers' proceedings. The main focus
will, inevitably, be on the subject of multiplicity, with special emphasis on
recent results regarding triple central star systems as well as wide binaries
which avoid a common-envelope phase. Furthermore, in light of the upcoming
release of Kepler's Campaign 11 data, I will discuss a few of the prospects
from that data including the unique possibility to detect merger products.
