Landlord/tenant law in Arizona?

I live in Maricopa County AZ. My mother was co-tenant on my lease. She passed away 06/22/11. Now I HAVE to move, but I'm in the middle of a 12 month lease. My landlord has no mercy-she says if I move out under ANY circumstances, I'm am breaking the lease-there is NO condition in which I can legally void my lease. Do I have any rights here? What happens if I just break the lease? Will I go go jail? Will I be blacklisted by all landlords in my area? At the very least can my landlord garnish my part-time wages? My mother died for gosh sake, isn't there something in the law to protect me? Greedy landlords seem to have the rights because they have the $$$ power to buy lawmakers. Thanks for all legit advice
