A Savage Lust,
1st in the Pride Brothers series [ETA: 3rd in the series due to publisher submission glitch; 1st & 2nd offered at discount pricing to make up for this, scroll down to bottom of thread for links] of shapeshifter ménage erotic romances by H.C. Brown, is All Romance eBooks' Earth Day countdown freebie for the 4th of April, courtesy of publisher Noble Romance.
The tags on this say m/m, m/f/m, BDSM (which incidentally makes it 3 out of 4 BDSM-containing offerings thus far), shapeshifters, multiple partners, and time-travel, so if this sounds like your kind of book, be sure to scoop it up before the offer expires just before the end of the 5th of April.
Direct link to product page here, and you can also still get the previous day's also paranormal shapeshifter romance,
Beowulf and Roxie, until just before midnight on the 4th.
Don't put both in your cart at the same time, because the automatic discount can only work on one of them at a time and you'll be asked to pay for the extra book during checkout. Do multiple check outs.
