Unknown sanserif from new Swedish teen novel

[Måns Berg]

This sans is used in the novel Jobbiga tjejer for the colophon and certain special text. Curiously, another sanserif font (FF Mark, I think) is used for the blurb of the same book. But this font differs in many details, most notably by having a two-storey <a> where the blurb font is one-storey.

I thought it might be Avenir, but the caps are all wrong. Any idea what this can be?

[Måns Berg]

Ping! Does no one know what font this is?

[Riccardo Sartori]

Gotham.

[Måns Berg]

Of course! Thanks a lot.
