  The exotic, neutron-rich and weakly-bound isotope $^{29}$F stands out as a
waymarker on the southern shore of the island of inversion, a portion of the
nuclear chart where the effects of nuclear forces lead to a reshuffling of the
single particle levels and to a reorganization of the nuclear structure far
from stability. This nucleus has become very popular, as new measurements allow
to refine theoretical models. We review the latest developments and suggest how
to further assess the structure by proposing predictions on electromagnetic
transitions that new experiments of Relativistic Coulomb Excitation should soon
become able to measure.
