Superman

"Superman is going through some changes. First, there's his new 'solar flare' power, which releases tremendous amounts of energy but leaves him functionally human--fragile, vulnerable, prone to hangovers--for 24 hours. But an even bigger change is coming. A new company called Hordr has sprung up, and its business is secrets. If you have one that you want to keep hidden, Hordr can control you--and no one has a bigger secret than Clark Kent"--Dust jacket.
