Sure thing (though it was my lovely wife that bought them, not me!):
- Systems Engineering Demystified by Jon Holt
- Essential Architecture and Principles of Systems Engineering by C. E. Dickerson & Siyuan Ji
- System Design & Management: An Introduction to Systems Engineering by Bob Parkinson
On a somewhat related note I also got Difference & Repetition by Deleuze and Process and Reality by Alfred North Whitehead, but they're more philosophical than practical.
If you're interested, drop me an email (in my bio) and I'll let you know, once I've read my new books, if they're any good.
