  We study the classical dynamics of black holes during a nonsingular
cosmological bounce. Taking a simple model of a nonsingular bouncing cosmology
driven by the combination of a ghost and ordinary scalar field, we use
nonlinear evolutions of the Einstein equations to follow rotating and
non-rotating black holes of different sizes through the bounce. The violation
of the null energy condition allows for a shrinking black hole event horizon
and we find that for sufficiently large black holes (relative to the minimum
Hubble radius) the black hole apparent horizon can disappear during the
contraction phase. Despite this, we show that most of the local cosmological
evolution remains largely unaffected by the presence of the black hole. We find
that, independently of the black hole's initial mass, the black hole's event
horizon persists throughout the bounce, and the late time dynamics consists of
an expanding universe with a black hole of mass comparable to its initial
value.
