The Society of Authors reports that Ticktock Books and Ticktock Direct and Ticktock Media have all gone into voluntary liquidation last year, but Ticktock Entertainment continues with a publishing imprint called Wise Walrus.
The Society suggest you get in touch with them before signing any deals with Wise Walrus or any company run by Managing Director John Twiggs.
I have no personal experience with these companies, but I have known of other companies that take your money, go into liquidation or bankruptcy, and then promptly start up again under a different name.
As a general guideline, always do a Google search of any company you are thinking of signing with. Be sure to go past the first page or two of search results because sometimes unscrupulous companies populate those with phoney blogs and websites.
