The Nightmare Years.

There were I believe three deals offered at various times by the Soviets. The last one was in May 1943 when Molotov actually met with German representatives and offered a return to the 1939 borders for peace.

The Germans were all set up for Kursk though and rejected the offer.
 
What would this peace deal look like? It's pure speculation, but seems reasonable (from the perspective of the time) that the USSR is pushed back to its pre-1939 borders (except with Finland) with the lands in question falling instead under German control, and Bessarabia likely returned to Romania.
