  We describe the properties of the neutron rich nuclei around N=28 in the
shell mode framework. The valence space comprises the $sd$ shell for protons an
the $pf$ shell for neutrons without any restriction. Good agreement is found
with the available experimental data. The N=28 shell closure, even if eroded
due to the large neutron excess, persists. The calculations predict that
$^{40}$S and $^{42}$S are deformed with $\beta=0.29 $ and $\beta=0.32$
respectively.
