I think Mozilla Firefox 184.108.40.206 and Loose-Id have incompatibility issues because every week one cover from the front page goes missing. I've notified the Loose-Id folks about this some two weeks ago and I'm told this is most likely a Firefox issue.
At any rate, this week's unlucky book cover that goes zapped is Annie Dean's My Valentine. See my screenshot:
I'm still debating on whether I should buy it because... dude, $7.99.
