When Calden wakes up – every time he wakes up – the last thing he can recall is a debilitating headache that even his medical background failed to identify as anything more serious than a regular headache. He also remembers his decision to ignore the fact that his best friend Eli is married and to tell him about his long-standing feelings for him. He remembers June second.
But it is not June second anymore. The tattoos on his arm and chest prove it. They also tell him why he doesn't remember anything past June second… and why Eli sleeps in his bed now.
When Calden wakes up – every time he wakes up – he gets to discover Eli is in love with him for the first time all over again.
