'jewish spirituality - a brief introduction for christians'
'Jeshua - a guide to the real Jesus & the original church'
'the sage from galilee - rediscovering Jesus' genius' (this last with a caveat from cj that it was a bit... sketchy)
i am looking forward to reading them... it's an area of study i have barely pursued at all, and think is quite fascinating. i'll keep you up to date with anything good or sketchy! :)
