Activist Boniface Mwangi has been one of Kenya's most influential and controversial personalities in the recent years.

Last year, he was caught up in a verbal altercation with Deputy President William Ruto, after he alleged that the DP was behind Jacob Juma's murder.

He was sued for that after he defiantly said that he wouldn't apologize to Ruto.

Months later, Boniface (who also wants to dip himself in the murky waters of politics) launched his biography titled 'Unbounded'. He went on to launch the book in America last week.

The launch was held in Washington DC. Kenyans living in Boston had organized the event.
