And Shai (thanking MM) mentioned Yuval Harari's new book on magic.
I thought I would just add one more, also published by Mosad Bialik, on behalf of Ben Gurion University of the Negev Press - three new works by Moses ibn Tibbon (belated hattip to R Eliezer Brodt of the Seforim blog). This 13th century scion of the famous family of translators and philosophers has received a fair amount of attention in recent years, with his commentary on Shir ha-Shirim published recently in German translation.
Colette Sirat announced long ago her intention of publishing his commentary on Talmudic aggadah, included in this volume (Sefer ha-Peah). 13th century Southern France produced a number of interesting commentaries on Talmudic aggadah as part of its grappling with philosophy, rationalism and allegory. One that has received some attention is that of R Isaac ben Yedaiah, as described by Marc Saperstein in 'Decoding the Rabbis'. R Menahem Meiri, everyone's favourite rationalist rabbi, did his fair share of explaining away weird aggadot. Saperstein also described the aggadic commentaries of Yedaiah ha-Penini (who wrote on a wider swath of compositions - Menahem Kahana in his doctorate praises the textual virtues of his citations of Sifre Numbers in his commentary ad loc). I'm curious to see which sugyot Moses ibn Tibbon chose.
Avraham Israel recently published Moses' commentary on Solomon ibn Gabirol's Azharot as part of his MA thesis, and it is included in the new volume. And Howard Kreisel, his advisor, seems to have published Sefer ha-Taninim. But I don't know anything about that.
