  The complexity of the antiferromagnetic orders observed in the honeycomb
iridates is a double-edged sword in the search for a quantum spin-liquid ground
state: both attesting that the magnetic interactions provide many of the
necessary ingredients, but simultaneously impeding access. As a result, focus
has been drawn to the unusual magnetic orders and the hints they provide to the
underlying spin correlations. However, the study of any particular broken
symmetry state generally provides little clue as to the possibilities of other
nearby ground states \cite{Anderson}. Here we use extreme magnetic fields to
reveal the extent of the spin correlations in $\gamma$-lithium iridate. We find
that a magnetic field with a small component along the magnetic easy-axis melts
long-range order, revealing a bistable, strongly correlated spin state. Far
from the usual destruction of antiferromagnetism via spin polarization, the
correlated spin state possesses only a small fraction of the total moment,
without evidence for long-range order up to the highest attainable magnetic
fields (>90 T).
