People have already pointed you to dmesg and /var/log/messages.

To receive an email every time it gets rebooted put the below lines
in /etc/rc.d/rc.local (or wrap them in a script and add a reference to

mail -s "Server <name> rebooted" you at example.com << ENDOFMESSAGE
Server <name> has been rebooted.

This of course will only notify you after the fact and will be no good
if the system stays down.
