  In the d-electron system YFe$_2$Ge$_2$, an unusually high and temperature
dependent Sommerfeld ratio of the specific heat capacity $C/T \sim
100~\mathrm{mJ/(molK^2)}$ and an anomalous power law temperature dependence of
the electrical resistivity $\rho \simeq \rho_0 + AT^{3/2}$ signal Fermi liquid
breakdown, probably connected to a close-by quantum critical point. Full
resistive transitions, accompanied by DC diamagnetic screening fractions of up
to 80\% suggest that pure samples of YFe$_2$Ge$_2$ superconduct below
$1.8~\mathrm{K}$.
