Does anyone know and recommend a good biography of Grothendieck?
(By good, I mean a biography that avoids the "crazy lone genius" tropism. )

On that page I really recommend
Comme Appelé du Néant -- As If Summoned From the Void (Part I) (Part II) A very interesting two-part article by Allyn Jackson, from the Notices of the AMS (Part I is in Vol 51, No. 4, Part II is in Vol 51, No. 10), full of anecdotes about Grothendieck's youth and professional life.
I highly recommend the 2-part article Joshua just recommended.
Great, thank you!
Scharlau's books are good, I think. You can get the first one 'Anarchy' here as a pdf, and the individual chapters of the other one 'Spirituality' on this page. These go with with the middle volume, by Leila Schneps 'Mathematics' (four chapters available here). The first volume is mostly about Grothendieck's parents and his childhood, the last volume is about his post-IHÉS life, up to the 1991 disappearance. (These are all at the page Julius linked)
I just discovered that Scharlau died in late 2020, so I don't know what happened to what I thought was a planned fourth volume...
