The Lean Startup, by Eric Ries

Excellent description of the genesis, theory and practice behind the movement. It documents the 'new' paradigm in how software should be produced, why and how it should now be done this way.

5/5.

Lean UX, by Jeff Gothelf and Josh Seiden

A decent read on lean theories for UI - specialized (obviously), and what it espouses sounds a bit of a lengthy process.

3/5.

Nuture Shock, by Po Bronson and Ashley Merryman

Excellent evidence-based discussions on kids and raising them. It's always good to debunk some myths with data from actual studies and I enjoyed the insights, not all of it was relevant to me (yet), but all interesting nonetheless.
Late summer 2013.

Succeeding With Agile, by Mike Cohn

Detailed examination of starting and being successful at Scrum. A little slow at the start because it describes how to start a transition (which wasn't relevant to me), but it soon got into its stride with team-building and scaling. Excellent experiences shared by the author and a tonne of interesting techniques to try. May-July 2013. 4/5.

Understanding A3 Thinking: A Critical Component of Toyota's PDCA Management System, by Durward K. Sobek II. and Art Smalley Superb explanation of a simple process in a concise but information-dense format that prompts readers to give it a try, in order to institute real change in a business environment. A few good points as to why this is more difficult in the West than in japan where it originated, which helps with understand the context and challenges. March-May 2013. 5/5.

Sabbath's Theater, by Phillip Roth

Salacious, scandalous and engrossing and uncomfortable as a result.; one man's attempted descent from peversity to depravity after the loss of his lover, the latest loss in his life. Speaks of the vitality of life, its decay, loss and grieving after. April-May 2013. 4/5.

The Big Book of Birth, by Erica Lyon and Donald Matheson

Forthright and honest, practical advice for those about to give birth. Lots of talk of using a doula during the process let it down somewhat, especially when the author is one herself, but very useful otherwise. March-April 2013. 3/5.
