The overall release pace is slower than ST, but individual series have shorter wait times between books.
And yet, when Pocket does a mini-series, they have
been known to come out one instalment per month, or even two instalments in the one month ("Gateways"; "New Earth"), or once three in the one month (""My Brother's Keeper").
The recent "Crucible" trilogy was three rather thick books only two months apart. The current "Terok Nor" trilogy is three books, one per month.
