HarperCollins Christian Published Kevin Malarkey's Second Book

Today, HarperCollins Christian Publishers released a marketing email聽for their heaven tourism book, Heaven Is for Real,聽in the face of the failure of Tyndale House’s book The Boy Who Came Back from Heaven. In short, HCC is standing behind the Colton and Todd Burpo’s story.
As it turns out, another one of HCC’s authors is Kevin Malarkey, the author of the now discredited The Boy Who Came Back from Heaven.
Marlarkey’s second book (with agent Matt Jacobson), titled Beautiful Defeat, is available now on the HCC website.
Alex Malarkey’s retraction undermined the credibility of the entire enterprise involving Kevin Malarkey and Matt Jacobson and so聽I wonder if the collapse of The Boy Who Came Back from Heaven presents any problems for HCC.
