"It's early days for the language so it's no surprise there's only a handful of books out there. Yet it's hard to see why you would need anything more than Agile Web Development with Rails. Programming books, in particular, rarely seem to answer queries straight away, but this one tackles the myths surrounding Rails straight off, and in plain English. But don't panic, it's not a Dummies guide - it will teach you how to use Rails to eliminate tedious web app configuration and, crucially, how to integrate it into AJAX." .NET, December 2005
