  It is widely accepted that curvature singularity resolution should be a
feature of quantum gravity. We present a class of time-dependent asymptotically
flat spherically symmetric metrics that model gravitational collapse in quantum
gravity. The metrics capture intuitions associated with the dynamics of
singularity resolution, and horizon formation and evaporation following a
matter bounce. A parameter in the metric associated with the speed of the
bounce determines black hole lifetime as a power of its mass; this includes the
Hawking evaporation time $M^{3}$.
