The super child, Miriam, has grown up and is perhaps falling in love. Yet Douglas, who used to be the leader of the teenage ruffians and is 9 years older than Miriam (though rumoured to have the mentality of a 17 year old) only sees her as a child. So! Douglas, stop the time and wait for me... while I go off to the next town, fall from a cliff, lose my memory, and find myself involved in a criminal intrigue!!!
Second of Miriam series.
