Heads towards the tonic using a circle of 5ths, but via IIx and ii. e.g: iii - VIx - IIx - ii - V - I.
It is worth mentioning this specifically, and not treating it as a general turnaround, because it has a character that is very much part of some tunes, especially when it dwells on the IIx longer than the other chords.
