Just did A Magician's Apprentice by Trudy Canavan. It's not exactly what I hoped for (wanted more magic, got a war in a different universe instead).

Currently I'm reading Foundryside by Robert Jackson Bennett like OP does. It's quite good so far. I feel entertained!
After that I either continue reading the other two following books or have a look at Imajica by Clive Barker or the Shades of Magic series by V. E. Schwab.

And after that I'll probably turn to sci-fi for a change.

If you like a to completely immerse into a different culture, history and time then maybe Ascendance of a Bookworm by Miya Kazuki is something for you. Don't let the manga style cover fool you it has really well thought-out world. It's the story of a girl that died in our world and was reborn in another while remembering her past life. As a bookworm she struggles with the harsh reality that books are incredible expensive over there and attempts to remedy that - and clashes with the prevailing culture and social norms. Sometimes the MC is a bit silly or too much coming-of-age. But I read 24 volumes (270-330 pages each) out of like 32 so it can't be too bad.
And yes they made an anime out of it.
