Query: A $\mathcal{N}=2$ Supersymmetric $AdS_4$ Solution in M-theory with
  Purely Magnetic Flux   We find a new $\mathcal{N}=2$ $AdS_4$ solution in M-theory supported by
purely magnetic flux via a sequence of abelian and non-abelian T-dualities.
This provides the second known example in this class besides the uplift of the
Pernici and Sezgin solution to 7d gauged supergravity constructed in the
eighties. We compute the free energy of the solution, and show that it scales
as $N^{3/2}$. It is intriguing that even though the natural holographic
interpretation is in terms of M5-branes wrapped on a special Lagrangian
3-cycle, this solution does not exhibit the expected $N^3$ behavior.
