I want to write a biography about a family member who led an inspiring life, but I need professional assistance to do justice to their story. I came across Penguin Publication’s biography writing services, but I’d like to know if they are any good.

Do they conduct in-depth research and interviews? How do they ensure the story remains authentic and engaging? I’d appreciate any feedback from those who have worked with them before.
