  A substantial fraction of Cataclysmic Variables (CVs) reveals non-solar
abundances. A comprehensive list of CVs which includes those that have been
examined for these abundances is given. Three possible sources of these
non-solar abundances on the secondary are accretion during the red giant common
envelope phase, an Evolved Main Sequence secondary and nova-processed material.
Use of the secondary's cross-section just on the escaping nova material to
change the abundances of its convective region has been the killing objection
for considering nova-processed material. The key element, ignored in other
studies, is that a thermonuclear runaway on a white dwarf causes a strong
propagating shock wave which not only ejects material, but also produces a
large amount of non-ejected material which forms a common envelope. This
nova-produced common envelope contains a large amount of non-solar material. We
demonstrate that the secondary has the capacity and time to re-accrete enough
of this material to acquire a significant non-solar convective region. This
same envelope interacting with the binary will produce a Frictional Angular
Momentum Loss which can be the Consequential Angular Momentum Loss needed for
the average CV white dwarf mass, WD mass accretion rates, the period minimum,
the orbital period distribution, and the space density of CVs problems. This
interaction will decrease the orbital period which can cause the recently
observed sudden period decreases across nova eruptions. A simple, rapid
evolutionary model of the secondary that includes the swept-up nova-produced
material and the increasing convective region is developed and applied to
individual CVs.
