I bought Programming in Ada 2005 (even though I am a poor student ;)) and found it quite useful (although it doesn't really explain certain concepts or why things are the way they are) You can also read about tasking at http://en.wikibooks.org/wiki/Ada_Programming/Tasking and http://en.wikibooks.org/wiki/Ada_Programming/Keywords/interface (some presentation about lego mindstorms during fosdem 2012 explains how tasking and Ravenscar profile works on embedded systems) Via a link in a post of somebody on this newsgroup to Globe_3D I found a course on concurrent and distributed systems of some Australian university which uses Ada; lecture 3 (synchronization) explains protected objects and Ada rendezvous (synchronous message-passing). I didn't know about entry families and suspension objects!
